Chapter 3 Access Restrictions
You may restrict access to specific shared folders, including external USB drives.
Notes:
• Access restrictions can be set separately for each shared folder, but not for folders within the shared folders.
• Configure access restrictions through Settings. Configuring access restrictions through Windows is not
supported and may cause unexpected behavior.
• You can also configure users, groups, and shared folders from Easy Admin by clicking Access Restrictions.
• Shared folders with limited access can still be used as backup destinations.
• If you change access restrictions for a user or group while they are accessing files, unexpected behavior may
result.
Adding a Shared Folder
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Click Create Folder.
21
4 Configure the desired settings, then click OK.
Notes:
• Names may contain up to 27 alphanumeric characters, hyphens (-), and underscores (_). Do not use a symbol
as the first character in a name.
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do
not use a symbol or space as the first character.
• You may create up to 400 shared folders.
• The names of shared folders should not use characters from more than one language. For example, mixing
Japanese and Korean characters in names is not supported.
• If multi-byte characters are used in shared folder names, configure the client language to match the
characters in Management - Name/Time/Language.
• The following characters are handled differently by Mac OS and Windows. Avoid using these characters when
sharing data between Mac OS and Windows:
• Windows does not support some characters that Mac OS and the TeraStation allow. If you create a filename
on a Mac with any of the following characters, it will not display correctly on a Windows computer. With
22
OS X 10.2 or later, you may have to connect to the TeraStation via AFP in order to display or copy any of the
following characters:
? [ ] / \ = + < > ; : " , | *
• Do not use any of the following words as the name of a shared folder. These words are reserved for internal
use by the TeraStation: info, spool, lost+found, global, printers, homes, lp, authtest, ram, msdfs_root, mt-
daapd, usbdisk# (where # is a number, for example: usbdisk1)
• Don't use the following unsupported characters in shared folder names, workgroup names, or filenames:
• File and folder names may contain up to 255 single-byte characters.
• Folder and workgroup names whose names contain non-Roman characters may not be displayed correctly.
• If shared folders are accessed from a Mac, information files for the Mac may be generated automatically. Do
not delete these files. If they are deleted using Windows, this may prevent further access from a Mac.
• If an SMB connection is used with OS X 10.3.9, the names of mounted volumes may appear as unreadable
characters in Finder and other applications. This is not a problem with the filename or data.
• With OS X 10.5 to 10.5.6, Spotlight searches are not supported over AFP connections. Use SMB connections or
upgrade to OS X 10.5.7 or later.
• The TeraStation belongs to the default zone in AppleShare; the zone cannot be specified.
• When files are copied to the TeraStation or to a USB drive connected to the TeraStation, file information such
as date created, date modified, and other date information may be updated or changed.
• During a file transfer, if settings are changed, the file transfer operation may be aborted.
• File copying to the TeraStation is protected by a journaling file system. If the Ethernet cable is disconnected
or a power outage occurs while copying data, the following may occur:
- Preset data such as the TeraStation name, users, and groups may be erased.
- An incomplete file may be copied and the file can no longer be deleted. If this happens, restart the
TeraStation, delete the file, and perform the copy operation again.
• The details for a shared folder may show that offline files are enabled for the folder even when they are
disabled for all folders. However, offline files really ware disabled correctly; it is only the details that are
wrong. This behavior will be corrected in a future firmware update.
Recycle Bin
To protect your data from accidental deletion, you may configure your TeraStation to use a recycle bin instead of
deleting files immediately. The recycle bin will only work with SMB connections. To empty the recycle bin, click File
Sharing - Folder Setup - Empty Recycle Bin in Settings.
23
Notes:
• You can prevent guests and other users from emptying the trash by navigating to File Sharing - SMB - Recycle
Bin Permissions and selecting "Administrator only".
• If you use Mac OS, enable "Exclude Mac OS temp files from recycle bin". If this setting is changed, files in the
recycle bin may be corrupted.
Read-only Shares
By default, new shares are set with read and write access, but you may change the attribute to Read Only in
Attribute. Read-only shares and HFS Plus formatted USB hard drives will have "Read-only" added to the shared folder
description.
Note: Configure read-only file attribute in Settings. Configuring them from within Windows is not supported
and may cause unexpected behavior.
Hidden Shares
If hidden shares is enabled, shared SMB folders will not be displayed in Network, and only certain users are allowed
to access them. To hide a shared SMB folder, follow the instructions below.
1 In Settings, navigate to File Sharing - Folder Setup and choose a shared folder or a USB drive to configure
hidden shares.
2 Check "Hidden Share (SMB Only)" and click OK.
Notes:
• If protocols other than "SMB" or "Backup" under "LAN Protocol Support" are enabled, the hidden shares
option will be grayed out and cannot be selected.
• Configure hidden share attribute in Settings. Configuring them from within Windows is not supported and
may cause unexpected behavior.
To access a hidden folder, open File Explorer in your computer and enter "\\TeraStation name\Shared folder name$\"
for the name. For example, if the TeraStation name is "TSXXX001" and the shared folder name is "share", enter "\\
TSXXX001\share$\" to open it.
Adding Users
Note: The TeraStation can register a maximum 300 of users, which includes the default users "admin" and
"guest".
1 In Settings, click File Sharing.
2 Click to the right of "Users".
3 Click Create User.
24
4 Enter the desired settings, then click OK.
Notes:
• Usernames may contain up to 128 characters, including hyphens (-), underscores (_), periods (.), !, #, &, @, $, *,
^, and %. Do not use a symbol as the first character.
• The user ID should be a number from 1000 to 1999. Each user ID should be unique. If this field is left blank, a
user ID is assigned automatically.
• Do not duplicate user IDs, group IDs, usernames, or group names. Each should be distinct and unique.
• The description may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces. Do
not use a symbol or space as the first character.
• Passwords may contain up to 20 alphanumeric characters and the following characters: - _ @ ! # $ % & ' ( ) * + ,
. / ; < > = ? " [ ] ^ { } | ~. Do not use a symbol other than an underscore (_) as the first character.
• Use the same username and password for both Windows and the TeraStation or you may not be able to
access shared folders.
• Do not use any of the following words as a username: root, bin, daemon, sys, adm, tty, disk, lp, sync,
shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none,
hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql
Importing User Information
You can import users in File Sharing - Users by clicking Import CSV File.
25
Format for user data: Username (required), password (required), and user description (optional).
Examples:
username1,password1,comment1
username2,password2,comment2
username3,password3,comment3
Guidelines:
• Use commas (,) as separators. Do not put spaces before or after commas.
• If a line has an incorrect format, the user on that line will not be registered.
• If a username already exists, the new user information will overwrite the old information.
• Do not use commas (,) in the username, password, or user description.
Note: Imported users are added to the "hdusers" group automatically.
Adding Groups
1 In Settings, click File Sharing.
2 Click to the right of "Groups".
3 Click Add Group.

Notes:
• Group names may contain up to 20 alphanumeric characters, hyphens (-), underscores (_), and periods (.). Do
not use a symbol other than an underscore (_) as the first character.
• Group descriptions may contain up to 75 alphanumeric characters, hyphens (-), underscores (_), and spaces.
Do not use a symbol or space as the first character.
• If the group ID field is left blank, a group ID is automatically assigned. Use numbers between 1000 and 1999
to set a group ID manually. Don't use duplicate group IDs.
• You may register up to 300 groups with the TeraStation.
• If you are logged in as a member of the general users group, you can only change your own password. If
you're logged in as an administrator, you can change any settings, including other users' passwords. If you are
logged in as a member of the power users group, you can create and edit shared folders, users, and groups.
• Do not use any of the following words as a group name: root, bin, daemon, sys, adm, tty, disk, lp, sync,
shutdown, halt, operator, nobody, mail, news, uucp, ftp, kmem, utmp, shadow, users, nogroup, all, none,
hdusers, admin, guest, man, www, sshd, administrator, ftpuser, apache, mysql

The TeraStation can join an Active Directory domain. Up to 1000 domain users and 1000 groups may be
downloaded from Active Directory.
Notes:
• The TeraStation supports a domain environment with a maximum of 1000 users and 1000 groups. 10,000
users and 10,000 groups can be downloaded from the domain controller but are not supported.
• If usernames or group names from Active Directory include multi-byte characters, you will not be able to
configure access restrictions for them.
1 In Settings, click Network.
2 Click to the right of "Workgroup/Domain".
3 Click Edit.
29
4 Select "Active Directory", then click Next.
5 Click Yes.
6 Enter the desired settings, then click OK.
7 Click to the right of "Folder Setup".
30
8 Click a shared folder that you want to set access restrictions for.
9 Click Edit.
10 Enable "Access Restrictions".
11 Select the level of access for the user or group.
: Read and write access allowed : Read access allowed : Access prohibited
12 Click OK.
Notes:
• To have the TeraStation join an Active Directory domain, configure it to use a DNS server that can resolve
names for the Active Directory domain.
• After building an Active Directory domain, the administrator password for joining the domain must be
changed at least once, or joining the Active Directory domain will fail.
• The DNS name and NetBIOS name of Active Directory domains should be identical.
• If both read-only and read and write permissions are given, the user will have read-only access. The most
restrictive access setting will apply.
• If there are more than 5 minutes difference between the TeraStation's clock and the domain controller's clock,
joining the domain or authenticating domain users and groups may fail. For best results, use an NTP server to
set the time for all network devices.
• To use the TeraStation as a member server in an Active Directory domain, the TeraStation should be logged
in to the domain and accessed from a computer that is not a member of the domain with a valid domain
account.
• If the TeraStation is a member server of an Active Directory domain, you cannot connect as a guest user via
AFP.
• If your TeraStation is a member server in an Active Directory domain and you change the authentication
method to "Workgroup", the account on the domain controller will not be deleted automatically.
• If FTP is enabled, local and domain group access restrictions from the AD network do not work. Use user
access restrictions instead.
31
• Don't disable the SMB protocol while Active Directory is used for access restrictions. If you do, you will need
to enable SMB again and reconfigure AD from scratch.
NT Domain
In an NT domain environment, the TeraStation uses account information from the NT domain server to set access
restrictions for files and folders on the TeraStation. There's no need to perform individual account management for
the TeraStation. If multiple TeraStations are installed on the network, the account information is centrally managed
in the NT domain, greatly reducing the operations required for installation and management.
Note: A maximum of 1000 domain users and 1000 groups can be downloaded from an NT domain server.
10,000 users and 10,000 groups can be downloaded from the domain controller but are not supported.
1 Create an account on the domain controller for the TeraStation.
2 In Settings, click Network.
3 Click to the right of "Workgroup/Domain".
4 Click Edit.
5 Select "NT Domain", then click Next.
Note: To use Active Directory from Windows 2000 or Windows Server 2003, select "Active Directory" instead of
"NT Domain".
6 Click Yes.
32
7 Enter settings and click OK.
8 Click to the right of "Folder Setup".
9 Click a shared folder for which you want to set access restrictions.
10 Click Edit.
11 Enable "Access Restrictions".
12 Select the level of access for "Domain Users" or "Domain Groups" you added.
: Read and write access allowed : Read access allowed : Access prohibited
13 Click OK.
33
Notes:
• If you change the TeraStation's name, you will no longer be able to use domain users and groups or access
restrictions. To repair this, rejoin the domain.
• If both read-only and read and write permissions are given to a user, the user will have read-only access.
• If a domain username is more than 20 bytes long, the TeraStation truncates it to 20 bytes.
• To use the TeraStation as a member server in an NT domain, the TeraStation should be logged in to the
domain and accessed from a computer that is not a member of the domain with a valid domain account.
• If the TeraStation is a member server of an NT domain, you cannot connect as a guest user via AFP.
• When you change the user or group settings on the domain controller, these changes may not take effect
immediately on the TeraStation until it is rebooted.
• If your TeraStation is a member server in an NT domain and you change the authentication method to
"Workgroup", the account on the domain controller will not be deleted automatically.
• If FTP is enabled, local and domain group access restrictions from the NT domain network do not work. Use
user access restrictions instead.
• Don't disable the SMB protocol while an NT domain server is used for access restrictions. If you do, you will
need to enable SMB again and reconfigure the NT domain settings from scratch.
User Authentication with an External SMB Server
TeraStations on your network can be linked to an external authentication server for centralized management of user
accounts and passwords. The authentication server should be another TeraStation or a LinkStation. Other external
SMB authentication servers are not supported.
Notes:
• Disable SMB2 before using external authentication.
• Access restrictions for local users and groups will still apply to shared folders if an external SMB server is used
for authentication.
• The procedure below contains methods to automatically register external users. You can also manually add
external users by converting them from local users. Refer to the "Converting Local Users into External Users"
section below for more details on converting local users.
1 In Settings, click Network.
2 Click to the right of "Workgroup/Domain".
3 Click Edit.
34
4 Select "Workgroup" and click Next.
5 If a prompt appears, click Yes.
6 Enter a workgroup name. Select "Assign authorization to external SMB server" and enter the SMB server's IP
address. You can also specify a server from another subnet.
7 If "Automatic user registration" is checked, users that access any of the TeraStation's folders will be
automatically registered as external users. This process only applies with folders that have access restrictions
disabled. After new external users are added, disable this option to limit the number of authenticated user
accounts.
8 If "Use shared folder for authorization testing" is checked, the TeraStation will automatically create a read-
only shared folder. Enter the shared folder name. Users that access this specific folder will be automatically
registered as external users. If this setting is de-selected at a later time, the TeraStation will automatically
remove the folder.
Note: Connect to the authentication folder via SMB, not FTP or AFP. Automatic user registration may not work
with OS X 10.8 (or later) the first time. If this occurs, try rebooting the TeraStation then access the authentication
shared folder again.
9 Click OK to save any changes. When saving changes to the external authentication server settings, you may
not to convert all current local users to external users. If a local user is converted to an external user, their user
35
information (including passwords) will be removed from the NAS. External users cannot be reverted to local
users.
10 Click to the right of "Folder Setup".
11 Click a shared folder to set access restrictions on.
12 Click Edit.
13 Enable "Access Restrictions".
14 Click on the External Users tab and select the level of access for each external user.
: Read and write access allowed : Read access allowed : Access prohibited
15 Click OK.
Notes:
• Users that are automatically registered belong to the "hdusers" group. They can be added to other groups
from within group settings. Added users will be listed in "Users" - "External Users". To delete a user that was
registered automatically, select that user and click Delete External User.
• If both read-only and read and write permissions are given to a user, the user will have read-only access.
• OS X 10.4 or earlier and Windows Server 2012 are not supported with external authentication.
• To access access-limited shared folders from OS X 10.7, use AFP instead of SMB; under "LAN Protocol
Support", check "AFP (Mac)" on the destination folders to use AFP and click OK.
• If access restrictions are set for users and groups from the authentication server, guest and anonymous
connections will not be possible with AFP connections.
• FTP connections do not support authentication with an external SMB server.
• If using a Windows PC for external authentication, the default Windows SMB security settings may need
to be changed. An easy way to do this is to run the File Sharing Security Level Change Tool, available from
36
this product's download page on the Buffalo website. This utility will let you easily change or restore your
Windows security settings to work with external authentication.
Converting Local Users into External Users
If using an external SMB server for authentication, you may convert any local users into external users. This way, the
TeraStation will have a user list that matches the users in the external SMB server, and access restrictions for this
TeraStation's shared folders may be assigned to the converted "external" users.
Follow the steps below to convert a local user into an external user. If a local user is converted, their user information
(including passwords) will be removed from the TeraStation. External users cannot be reverted to local users.
Note: External authentication should be enabled before local users can be converted. For more information on
external authentication, refer to the "User Authentication with an External SMB Server" section.
1 In Settings, click File Sharing.
2 Click to the right of "Users".
3 In the user list screen, check any users to be converted to an external user, then click Convert to External User.
4 Enter the confirmation number and click OK.
Converted users are displayed under the "External Users" tab. You can then configure access restrictions for external
users.

Chapter 4 Managing Storage
RAID Arrays
The default RAID mode is RAID 1.
Notes:
• If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter.
Always back up any important data before performing actions that affect your RAID array.
• Hard drive capacity is shown in Settings in actual gigabytes. The Properties window in Windows may show
GiB instead, which will be a smaller number.
• After the RAID mode is changed (except when creating a RAID 0 array or JBOD), the TeraStation performs
a RAID check that will take about 10 hours per TB. File transfers are slower during this period. While the I17
message is displayed on the LCD panel, do not turn off the TeraStation. If you do, the RAID check starts over.
• If the TeraStation is restarted or shut down while changing the RAID mode, the message displayed on the
LCD panel will change from I46 or I47 to I18.
RAID 1
Combines 2 drives into a mirrored array. The available space in the array is the capacity of a single drive. Identical
data is written to each drive. If a drive is damaged, data can be recovered by replacing the damaged drive. As long
as one drive in the array remains undamaged, all data in the array can be recovered.
RAID 0
Combines 2 drives into a single array. The usable disk space is the total space of all drives used. This simple RAID
mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all data
in the array is lost.
JBOD
This mode uses the hard drives inside the TeraStation as individual drives. The disk space you can use is the total
capacity of all drives in the TeraStation. If any drive is damaged, then the data on that drive is lost.
Working with RAID Arrays
To change RAID settings, navigate to Drives - RAID in Settings.
Using JBOD
With JBOD, each hard drive in the TeraStation is addressed separately. To put drives from an array into JBOD, follow
the steps below.
38
1 In Settings, click Drives.
2 Click to the right of "RAID".
3 Click the array to delete.
4 Click Delete RAID Array.
Once JBOD is configured, create shared folders on each drive to use them.
Changing RAID Mode
To change the RAID mode, first put the drives in JBOD.
1 In Settings, click Drives.
2 Click to the right of "RAID".
39
3 Click the array to delete. If the "RAID Mode" field is blank, the array is already in JBOD. Proceed to step 7.
4 Click Delete RAID Array.
5 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
6 Click OK.
7 Choose a RAID array.
8 Select a RAID mode and the drives to be used, then click Create RAID Array.
Note: Normally, after a RAID array is created, it is "resynced", which optimizes the array, making it more stable.
The resyncing process takes about 1 hour per terabyte of space in the array. File transfers will be slower
during this period, but the array will remain fully usable. The I17 message will be shown on the LCD display
during the resync. If you uncheck "Resync after creating the RAID array", the resync will be skipped. This is not
40
recommended for RAID 5 arrays, which should always be resynced. Resyncing is not needed for RAID 0 arrays. If
the TeraStation is rebooted during the resyncing process, the resync will begin again from the beginning.
9 Step through the wizard to create the array.
Notes:
• You can also configure RAID settings from Easy Admin.
• After changing the RAID mode, create a shared folder.
RMM (RAID Mode Manager)
With RMM, you can create or expand a RAID array without erasing the data on the drives.
To configure RMM, hard drives that aren't in a RAID array show "Normal". You must have both drives available in
JBOD (not in a RAID array) to build the RAID 1 array with RMM.
1 In Settings, click Drives.
2 Click to the right of "RAID".
3 Choose a RAID array.
4 Set the RAID mode to "RAID 1".
41
5 Check "Add a disk to RAID array with RMM. Your data will be preserved.".
6 Select the drive whose data will be saved from the drop-down menu.
7 Select the drive to add to the RAID array.
8 Click Create RAID Array.
9 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
RAID Scanning
A RAID scan checks you RAID array for bad sectors and if it finds any it automatically repairs them. RAID 1 array is
supported. For best results, run a RAID scan regularly.
1 In Settings, click Drives.
2 Move the RAID scanning switch to the position to enable RAID scanning.
3 Click to the right of "RAID Scanning".
4 Click Edit.
42
5 Select when to run the scan and click OK.
Notes:
• Check "Immediately" to run a RAID scan immediately.
• To stop a RAID scan, click Cancel RAID Scan.
Adding an External Hard Drive
Connecting an External Drive
Your TeraStation includes USB ports (the number of ports depends on your model), and you can connect external
drives to these ports. Once connected, they appear as shared folders on the TeraStation. Formatted drives are
detected automatically. Unformatted drives should be formatted in Settings.
After a USB drive is recognized, Windows adds "usbdisk X" under the TeraStation in "Network", where "X" is the USB
port where the hard drive is connected.
Compatibility
The following USB devices are supported by the TeraStation:
• USB storage devices
• Card readers (except for card readers that can recognize two or more memory cards)
Buffalo external USB drives are recommended but DUB and DIU series drives are not supported.
Supported file systems for external drives are below:
• FAT32
• EXT3
• XFS
• NTFS
• HFS Plus (read-only)
Connect only one device to each USB port of the TeraStation. Some external drives with automatic power-on don't
turn on automatically when connected to the TeraStation. Use their manual power switch to turn them on. Do not
connect bus-powered device to this TeraStation model. If there is insufficient bus power for your USB drive, connect
its AC adapter. Note that only the first partition of a connected USB hard drive is mounted. Additional partitions are
not recognized.
Notes:
• Backup data from Mac OS may include characters that cannot be written to FAT16 or FAT32 drives such as
".DS_Store". For best results, reformat the drive before using it as a backup target.
• If your USB 3.0 hard drive is not reconfigured after rebooting the TeraStation, unplug and reconnect it.
43
Dismounting Drives
If the TeraStation is powered on, dismount drives (internal and external) before unplugging them. You may
dismount external drives with the function button, or any drive from Settings. If the TeraStation is off, then all drives
are already dismounted and may be unplugged safely.
Note: Do not dismount internal drives while a RAID array is rebuilding or RMM is being configured. If you do,
data on the drives may be lost.
Dismounting with the Function Button
Hold down the function button for 8 seconds. The function button will light up blue for 30 seconds as your USB
drives are dismounted. When the dismount is finished, the function button's LED will turn off, then come back on.
You may now unplug any USB drives safely.
Note: After 60 seconds, the function LED will go out and any drives that have not yet been unplugged will be
remounted.
Dismounting from Settings
1 In Settings, click Drives.
2 Click Drives to dismount an internal drive or USB Drives to dismount an external drive.
3 Select the drive to dismount and click Dismount Disk.
44
4 When the following message is displayed, it is safe to unplug the drive.
Note: To remount the drive, unplug it and then plug it back in.
Checking Drives
A disk check tests the data on a drive in the TeraStation or connected via USB for integrity. Errors are fixed
automatically. With large drives, a disk check may run for many hours. Shared folders cannot be accessed during
a disk check. Do not turn off the TeraStation until the disk check is finished. Use the procedure below to run a disk
check.
1 In Settings, click Drives.
2 Select Drives to check an internal drive or USB Drives to check an external drive.
45
3 Select the drive to test, then click Check Disk.
4 Click Check. You have the option of deleting information files from Mac OS during the check if desired.
Formatting Drives
Note: Under some circumstances, data deleted when a drive is formatted can be recovered. To ensure that data
is "gone forever", a format might not be sufficient. See the "Erase Data on the TeraStation Completely" section
below.
1 In Settings, click Drives.
2 Select Drives to format an internal drive or USB Drives to format an external drive.
46
3 Select the drive to format, then click Format Disk.
4 Select a format type, then click Format.
5 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
6 Depending on the size of your drive, the format may take several minutes or several hours to complete.
"Formatting" will be displayed on the LCD display until the format is complete.
Notes:
• Do not turn off or disconnect power to the TeraStation while formatting a hard drive.
• For drives of 2.2 TB or larger, make sure that the "GPT Partition" checkbox is selected.
47
Encrypting Drives
Internal drives (and arrays) can be encrypted with 128-bit AES during formatting. Encrypted drives and arrays are
then readable only from that specific TeraStation. To unencrypt a drive or array, uncheck "Encryption" and format it
again.
Media Cartridges
If configured as a media cartridge, an internal drive can be used as a removable storage device in the same way as
an external drive. Media cartridges can be unplugged and connected to a different TeraStation with all data intact.
To configure a drive as a media cartridge, check "Media Cartridge" during formatting. To return it to its original state,
uncheck "Media Cartridge" and reformat the drive.
48
Media cartridges do not support:
• RAID arrays
• LVM volumes
• Access restrictions
• Direct connection to a Windows computer
Erase Data on the TeraStation Completely
Under some circumstances, data from formatted drives can be recovered. The disk erasure process in this section
does a much more thorough job of erasing data. This procedure is recommended for removing all data from a drive
in a way that makes it nearly impossible to recover with current tools. All data on the drives is completely erased.
The TeraStation will then be in the following state:
• Both drives in JBOD
• An empty shared folder on each drive
• All settings returned to their default values
• All logs deleted
If you remove a drive and then erase all data on the TeraStation, the LCD will show the E22 error message and the
number of the removed drive. You can still use the TeraStation.
1 In Settings, click Management.
2 Click to the right of "Restore/Erase".
3 Click Erase TeraStation.
4 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
5 All data on the TeraStation will be permanently erased.
Disk Quotas
You can set a disk quota to limit drive space for each user or group. You can also set an alert space. If the drive space
exceeds the set alert space, an email notification is sent. To configure email notifications for disk quota, refer to the
"Email Notification" section in chapter 10.
Notes:
• When using quotas, disable the recycle bin or empty the trash folder often. The limited space includes the
space used for trash.
• Quotas apply per drive or per array. If a quota is set to 1 GB, each array or drive can use a maximum of 1 GB.
49
• Quotas cannot be set for external hard drives connected to the TeraStation and hard drives that are
configured as media cartridges.
• If both user and group quotas are configured for a user, the most restrictive quota will always apply.
Quotas for Users
Follow this procedure to limit the shared folder disk space available for a user.
1 In Settings, click File Sharing.
2 Click to the right of "Users".
3 Select the user whose space will be limited.
4 Enable quotas, choose the maximum space the user will be allowed to use, and click OK.

15 Select the volume that you created and click OK.
Note: If an LVM volume could not be mounted, try restarting the TeraStation. If an issue still exists, delete and
recreate the LVM volume. Deleting the LVM volume will erase data on the volume.
53
Using the TeraStation as an iSCSI Device
Introduction
iSCSI is a protocol for carrying SCSI commands over IP networks. Unlike traditional SAN protocols such as Fibre
Channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network
infrastructure. Normal Windows formatting such as NTFS is supported.
Differences Between NAS and iSCSI
With iSCSI, the TeraStation is connected to a single computer, such as a server. Other computers on the network
access files on the TeraStation through the computer it's connected to. The TeraStation can be used as a local drive
from Windows Server. Features of Windows Server such as Active Directory can be used normally.
As a NAS, the TeraStation is a server, and computers (including other servers) on the network can access shared
folders on it directly. A separate server is not required, and features such as backup are built-in.
Network Configuration
Use gigabit or faster network equipment with iSCSI. For best results, a dedicated network for iSCSI is recommended,
separate from the regular network. Use fixed IP addresses for storage devices such as the TeraStation.
Installing a Connection Tool
Windows XP, Windows Server 2003
Before using any iSCSI equipment, download and install the iSCSI connection software "Microsoft iSCSI Software
Initiator" from the Microsoft website. You can also use Buffalo iSCSI Connection Tool to connect an iSCSI hard drive.
Windows Vista or later, Windows Server 2008 or later
The Microsoft iSCSI Software Initiator is already installed on your computer. You don't need to download and install
it. You can also use Buffalo iSCSI Connection Tool to connect an iSCSI hard drive.
Note: On Windows 10, Buffalo iSCSI Connection Tool won't work. Use Microsoft iSCSI Software Initiator.
Creating a iSCSI Volume
To use the TeraStation as an iSCSI hard drive, create a volume first. Configure the TeraStation as described below.
Notes:
• If the LVM settings are changed, all data on the volume will be erased. Before changing any settings, back up
any important data.
• The TeraStation can have up to 255 volumes, but we recommend using only a maximum of 32. Exceeding this
volume amount may cause irreparable damage to the unit.
1 In Settings, click Drives.
Note: Steps 2–6 below describe the procedure to enable LVM for specifying a volume size or changing it later.
LVM does not need to be enabled for a drive to be used as an iSCSI hard drive, as you can still create an iSCSI
volume from the entire drive or array. However, enabling LVM is recommended for drives that will be used for
iSCSI.
To use whole drive or array as an iSCSI hard drive, skip to step 7.
54
2 Click to the right of "LVM".
3 Select the drive or array where the volume will be created and click Enable LVM on Volume.
4 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
5 Click OK.
6 Click Close.
Note: If you click Show under "Volume List", the volumes will be listed on the screen and you can see if these
volumes are being used as iSCSI or NAS.
55
7 Move the iSCSI switch to the position to enable iSCSI.
8 Click to the right of "iSCSI".
9 Click Create Volume.
10 Enter a volume name, volume description, volume, and size (if you enabled LVM), then click OK.
The volume size that you specify here can be changed later. To change the volume size, refer to the "Expanding
Volume Sizes" section below.
11 The "Confirm Operation" screen will open. Enter the confirmation number, then click OK.
12 Click OK, then Close.
Creating an iSCSI volume is finished.
Note: If you click Disable Connection for the selected volume in Drives - iSCSI in Settings, the selected iSCSI
volume can no longer be accessed. If you click Enable Connection, the volume will become accessible from the
iSCSI initiator software.
Connecting or Disconnecting Volumes
There are two methods to connect or disconnect volumes. One uses the pre-installed Microsoft iSCSI Initiator on
Windows; the other uses Buffalo iSCSI Connection Tool.
Note: By default, the IP address of the TeraStation is automatically assigned from a DHCP server. However, in
this case, if you turn off and restart the TeraStation, the IP address may be changed and the volumes on the
TeraStation may not be accessible. To avoid changing the IP address unexpectedly, using a fixed IP address for
the TeraStation is recommended.
Using Microsoft iSCSI Initiator
Connecting Volumes
To connect a volume using Microsoft iSCSI Initiator from a Windows computer, follow the procedure below.
Note: Do not shut down the TeraStation while connecting to an iSCSI volume. It may cause unexpected data
erasure. Make sure all connections are disconnected before shutdown.

multiple computers cannot be accessed from one volume (or one drive) at the same time.
Checking Whether iSCSI Volume is Connected
To check whether an iSCSI volume is connected, navigate to Drives - iSCSI. Current volumes will be listed. If
"Connected" is displayed under "Connection", the volume is currently connected from the client.
Configuring Access Restrictions
A username and password can be configured for the entire iSCSI volume or each existing volume. Access restrictions
can be configured so that entering a username and password is required for each connection.
The TeraStation can perform mutual authentication (two-way authentication). Dual passwords ensure that only
authorized client computers can access the volume on the TeraStation.
Follow the procedure below to enable access restrictions.

Hard Drive Replacement
Hard drives in the TeraStation show a blue status LED during normal operation. If a drive fails, its error LED will glow
red.
1
2
1 Error LED
Glows red if a drive has failed.
72
2 Status LEDs
The failed drive's status LED will be glowing a steady red. A drive with a red status LED is ready to hot-swap.
Notes:
• Do not unplug a drive whose status LED is green instead of red. Dismount it first or shut down the TeraStation
before swapping a working drive. If you remove the drive without properly dismounting it, data may be lost
or the TeraStation may malfunction.
• For the replacement drive, use a Buffalo OP-HDWR series drive for the TS5200DS and a OP-HDWP series drive
for the TS5200DSP. The new drive should be the same size (or larger) as the replacement drive. If a larger drive
is used, the extra space will not be usable in a RAID array.
• To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of
metal before handling any sensitive electronic parts.
• After a drive is replaced, it will take about 30 minutes before normal file reading and writing are restored.
Settings may not be accessible during this period.
• Do not change the order of the hard drives in the TeraStation. For example, pulling out drive 1 and replacing
it with drive 2 may cause data to be corrupted or lost.
• If the LCD display does not change after a new drive is installed, click Rediscover Disk in Settings.

unplugging the drive, dismount it in Settings or shut down the TeraStation.
Replacing a Non-Malfunctioning Hard Drive
Do not replace a hard drive that is not malfunctioning (unless it has been converted to a media cartridge).
If you must change a drive that is not malfunctioning, either first dismount it in Settings, referring to the
"Dismounting Drives" section above, or shut down the TeraStation before replacing the drive. Even if you want to
replace more than one drive at the same time, replace drive one at a time to preserve your data. When replacing the
non-malfunctioning drive, data or RAID array will be function as below:
Operating in RAID 0 Mode
All data on the RAID array will be deleted after replacing the drive. You will not be able to use the TeraStation until
you delete and rebuild the RAID array with the new drive.
Operating in JBOD
All data on that hard drive will be deleted after replacing the drive. You will not be able to use the TeraStation until
you format the new drive.
Operating in RAID 1 Mode
If you are using RAID 1, the RAID array will be in degraded mode after replacing the drive. You will not be able to use
the TeraStation until you rebuild the RAID array with the new drive.

Chapter 5 Backup
Back Up from the TeraStation
You can back up TeraStation folders to:
• A different folder on the TeraStation
• Another LinkStation on the network
• Another TeraStation on the network
You can also configure backup jobs from Easy Admin.
Preparing a Backup Destination
First, configure a folder as a backup destination.
1 In Settings, click File Sharing.
2 Click to the right of "Folder Setup".
3 Choose the folder to set as a backup destination.
4 Click Edit.
5 Under "LAN Protocol Support", check "Backup" and click OK.
Note: To configure a password, enter it into the "Remote Backup Password" field. Leave this field blank if you
don't want a password. If the target device is configured with a backup password, you can easily find the backup
target folder during configuration of the backup job by searching for the password.
Backing up to a LinkStation or TeraStation on another network when connected by
a VPN
You can back up to a LinkStation or TeraStation on another network as long as the two networks are connected by a
VPN. Follow this procedure to enter the IP address or hostname of the target LinkStation or TeraStation.
1 In Settings, click Backup.
77
2 Click to the right of "Backup".
3 Click List of LinkStations and TeraStations.
78
4 Click Add under "Off-subnet Devices", enter the IP address or hostname of the target LinkStation or TeraStation,
and click Close.
If your setup meets the requirements below, you don't have to configure these settings:
• The source and target TeraStations are on the same network.
• No backup password is set for the target TeraStation.
• No TeraStation from outside the subnet or connected by a VPN, is used.
Notes:
• To back up data between LinkStations or TeraStations on a network using jumbo frames, make sure that
both devices are configured to use identical (or similar) Ethernet frame sizes. If Ethernet frame sizes are
significantly different, the backup job may not be properly performed. In such a case, select the default frame
size (1518 bytes).
• You can also specify hostname by a fully qualified domain name (FQDN).
• Windows-based TeraStations with multibyte characters in the hostname may not be detected as a backup
target, and folders in these devices cannot be used as backup target folders.
Configuring a Backup Job
1 In Settings, click Backup.
2 Click to the right of "Backup".
79
3 Click Create New Job.
Note: Up to 8 backup jobs can be configured.
4 Select backup settings such as date and time to run.
The following types of backup jobs may be selected:
80
Type Files included
Normal backup All files in the source will be backed up to the destination.
Overwrite (incremental)
The first time the backup job runs like a normal backup. In subsequent
backups, files added to the source as well as files deleted from the source are
kept in the backup folder.
Overwrite (differential)
The first backup job runs like a normal backup. As each additional backup
job runs, files are added to and deleted from the backup folder. The backup
destination folder is always the same size as the backup source folder.
Management backup
Each time a backup is executed, management information is stored, and
only files that have changed are copied or deleted. Data is retrieved from
the previous backup file for files that were not changed. This is useful for
making backups with limited space or for referencing status at a particular
point in time (for use for data snapshot applications). The destination folder
for a management backup should be a local folder on this TeraStation or on a
USB drive attached to it. The target folder will be set to read-only. Do not use
folders from drives formatted with FAT.
You can specify how many backup versions to keep from 1–400, or select
"Unlimited" to keep all backups until the drive is full. If a specific number of
backup versions is specified, the backup destination folder should be on the
same TeraStation that the backup job is configured from, or on an external
USB drive attached to that TeraStation.
5 Click Add.
6 Click Browse under "Backup Source Folder Name".
7 Select the shared folder that will be the backup source, then click OK.
8 Click Browse under "Backup Target Folder Name".
81
9 Select the backup target and click OK.
Note: If you will use the same folder for both Amazon S3 remote replication and as a backup target folder,
create a new subfolder under "\wbfs\amazons3". Under "LAN Protocol Support", enable "Backup". Without these
settings, that shared folder will not be listed in the backup target folder list.
10 Click OK. Jobs added to "Backup List" are displayed.
11 Click Close.
Replication
Replication copies all data from a share to a share on a different TeraStation. This is an easy way to configure a
reliable system to provide data protection in the event your main TeraStation fails. To configure replication, connect
an Ethernet cable to the LAN port of each TeraStation and follow the steps below.
Notes:
• For best results, use static IP addresses for both replication TeraStations (source and target).
• Replication source data is copied to the replication target folder with a differential overwrite. Any data that is
not in the replication source will be overwritten.
Preparing a Replication Destination
First, configure a folder as a replication destination.
1 In Settings, click File Sharing.
82
2 Click to the right of "Folder Setup".
3 Choose the folder to set as a replication destination.
4 Click Edit.
5 Under "LAN Protocol Support", check "Backup" and click OK.
Note: Do not configure a backup password for the shared folders. Folders with a backup password set cannot be
selected as replication targets.
Configuring a Replication Job
1 In Settings, click Backup.
2 Click to the right of "Replication".
3 Click Edit.
83
4 Click Add.
5 Click Browse under "Replication Source".
6 Select the shared folder that will be the replication source, then click OK.
7 Click Browse under "Replication Target".
84
8 Select the shared folder that will be the replication target, then click OK.
9 Click OK.
10 Click Yes.
Notes:
• A maximum of 64 shared folders can be configured for replication.
• Replication can also be used to copy all data from a share to a share on an attached external drive. Format
the drive with ext3 or XFS before using it for replication. Drives with FAT32 partitions are not supported with
replication.
• You can select subfolders as the replication source. Folders whose names contain more than 80 alphanumeric
characters cannot be selected.
• Don't use the same TeraStation for both failover and replication, or replication and Time Machine.
• Don't configure replication from one source folder to multiple target folders.
• If replication is configured via LAN port 2 and DHCP is used, the TeraStations may not automatically recover
from network disconnection. If this happens, restart the TeraStations. For best results, give both replication
TeraStations static IP addresses.
85
• If a network problem causes a replication error, unsynced data may be shown as "0" even though replication
is incomplete. Click Sync to recover from the replication error. All files from the source folder will be copied to
the target folder.
Failover
With failover, two TeraStations are connected to the network for redundancy. If an issue renders the main
TeraStation inaccessible, operation automatically switches to the backup TeraStation.
Failover will activate during any of the following situations:
• The backup TeraStation cannot detect the main TeraStation within a specified time
If the backup TeraStation has not received a packet from the main TeraStation within a specified time, the backup
TeraStation considers the main TeraStation to have failed. By default, it will try 5 times and wait 60 seconds. If this
is triggered by accident, reconfigure failover from the main TeraStation.
• Errors
Failover will occur if any of the following errors occur:
E12 (cooling failure), E14 (cannot mount RAID array), E16 (drive not found), E22 (cannot mount drive), E30 (drive
failure)
Notes:
• Only use identical model and capacity TeraStations for failover. If the capacity of the main TeraStation is larger
than that of the backup TeraStation, an I33 replication error will occur.
• All drive bays of a TeraStation should be occupied if it will be used for failover. Failover will not work if a drive
is missing from any bay.
86
Usage Restrictions
Functional Restrictions
Failover is not available when any of the following functions are enabled:
Replication, sleep mode, encrypted disk volume, MySQL server, media cartridge, LVM volume, iSCSI volume, port
trunking, cloud storage, surveillance server, hot spare, access restrictions by Active Directory or NT domain
Setting Restrictions
The following functions will not be available while failover is enabled:
Initializing settings, changing the RAID settings, formatting drives, iSCSI volume, changing the backup unit's
settings, turning the TeraStation on and off, updating the firmware.
While failover is enabled, shutdown, power-on, and firmware update operations can be made available by
temporarily changing the TeraStation to maintenance mode. Maintenance mode can be enabled or disabled at
Backup - Failover in the main TeraStation's Settings. Click Maintenance mode to enable maintenance mode, or click
Cancel maintenance mode to disable maintenance mode.
To update the firmware while in maintenance mode, the main TeraStation can be updated from Settings, but the
backup TeraStation cannot. Download the firmware updater from the Buffalo website for the backup TeraStation
and try updating the firmware through it.
Non-Transferable Settings
The settings below are not copied from the main TeraStation to the backup TeraStation. Make a note of the original
settings so that they can be configured manually if failover errors.
Web server (including PHP), MySQL server, Direct Copy, WebAccess*, print server, UPS synchronization, antivirus**
* After failover, re-register your BuffaloNAS.com account for WebAccess on the new main TeraStation if LAN port 1 is
assigned a new static IP address or using DHCP. If the new main TeraStation inherits the original static IP address for
LAN port 1, WebAccess settings will be transferred and you will not need to reconfigure it.
** Only if the antivirus is activated on the TeraStation.
Using with UPS
Once failover is configured, you cannot set up a UPS for the backup TeraStation. Configure your UPS before
configuring failover. UPS recovery can be configured for both the main and backup TeraStations. However, the UPS
settings of the main TeraStation will not be copied to the backup TeraStation.
If the backup TeraStation is configured to sync with the UPS connected to the main TeraStation, and the main
TeraStation becomes unavailable, the backup TeraStation will not be able to detect a power outage. In this case,
move the UPS cable from the main TeraStation to the backup TeraStation and reconfigure the UPS link settings.
Configuring Failover
There are two ways to set up a connection for failover. Regardless of configuration, during failover the backup
TeraStation will assume the name and IP address of the main TeraStation, unless a "service IP address" is set for the
backup TeraStation unit during failover configuration. The "service IP address" will be the new address of the backup
TeraStation when it takes over operation from the main TeraStation.
It is recommended that both TeraStations are configured with static IP addresses for the purposes of failover.
Otherwise, if the main TeraStation becomes inaccessible and later comes back online, an IP conflict may occur.
87
Using LAN port 1 for both failover and connecting to the network
Using this setup, if the main TeraStation fails, the backup TeraStation will replace it completely. The backup
TeraStation will be updated over normal network traffic.
Using LAN port 1 for connecting to the network and LAN port 2 for failover
With the second setup, the backup TeraStation and main TeraStation are connected by a second Ethernet cable
connecting their LAN 2 ports. Updating is done over this dedicated network path, so updates are quicker and don't
interfere with normal network traffic.
Configuration
1 In Settings for the main TeraStation, click Backup.
2 Click to the right of "Failover".
3 Click Edit Failover Status.
88
4 Select a TeraStation to be the target backup device.
5 Enter the administrator password of the target backup device, then click Continue.
6 If the administrator password is correct, the backup TeraStation will beep. To accept the settings from the main
TeraStation, hold down the function button on the front of the backup TeraStation until it stops beeping.
7 The I51 message will display on the LCD display and NAS Navigator2 for both TeraStations. Wait until
initialization finishes. Failover is configured after it finishes and the I51 message disappears.
8 To avoid a possible IP conflict after failover occurs, configuring a service IP address from the main TeraStation's
Settings is recommended.
Notes:
• If replication is configured for more than one folder, initialize the TeraStation before configuring failover.
• The main TeraStation cannot be used as the backup location for Time Machine.
• Do not use the same TeraStation for both failover and replication, or failover and Time Machine.
• If email notification is enabled and failover occurs, navigate to Management - Email Notification - Edit in the
main TeraStation's Settings and click OK.
• Email notification settings will revert to the default settings after failover. Notification emails will be sent
at midnight by default. Reconfigure email notification after the backup TeraStation replaces the main
TeraStation.
• Ethernet frame size settings for main and backup TeraStations should be 1500 bytes. To change the Ethernet
frame size, navigate to Network - IP Address, click the LAN port and Edit, and change the Ethernet frame size to
"1500" bytes.
• Files whose filenames contain more than 80 alphanumeric characters will not be backed up.
• If the I33 error message appears on the LCD display, navigate to Backup - Replication and click Resync.
• If failover occurs unexpectedly due to issues such as network problems, even if neither TeraStation has failed,
log in to both the main and backup TeraStations' Settings interface, reset the failover settings, and configure
it again.
• The RAID array on the backup TeraStation may be reconfigured and resynchronized as part of the failover
configuration process. This is expected behavior and not an error.
Switching to the Backup Unit Manually
If "Switch to backup unit manually" is selected in Settings, the backup TeraStation will not replace the main
TeraStation if the main TeraStation fails. To have the backup TeraStation replace the main TeraStation, you can either:
• Log in to Settings for the backup TeraStation and click Set as Main Unit.
89
• Or, press and hold down the function button on the backup TeraStation.
Reconfiguring Failover is No Service IP Address was Set
When the backup TeraStation replaces to the main TeraStation, the I49 message may appear on the backup
TeraStation's LCD display and in NAS Navigator2.
If you did not set a service IP address and failover occurs, it is recommended that you manually reconfigure failover
for both TeraStation units, assuming the original main TeraStation is still viable. This should be done as soon as
possible after failover occurs in case the original main TeraStation comes online, which might create an IP conflict.
If the original main TeraStation is no longer viable but you have replacement ready, refer to the "Configuring
Failover" section above.
1 After failover occurs, log in to Settings for the current main TeraStation.
2 Click to the right of "Failover".
3 Force failover to stop.
4 Log out of Settings and shut down this TeraStation.
5 If the original main TeraStation is fully functional, connect it to the network and powered it on.
6 Rename the unit and configure the IP address so that it has a new static IP address.
7 Power on the current main TeraStation. With the two units on the same network, reconfigure failover with the
units' former roles reversed, referring the "Configuring Failover" section above.

TeraStation.
• After receiving the Wake-on-LAN packet, the TeraStation may take approximately five minutes to be ready to
use.
• To use Wake-on-LAN, you'll need Wake-on-LAN software. The TeraStation does not include Wake-on-LAN
software.
160
• The TeraStation does not support using Wake-on-LAN and port trunking at the same time. You may use either
feature, but not both at the same time.
• On the local network, Wake-on-LAN packets may be sent to port 2304 on either of the TeraStation's LAN
ports. If the TeraStation is connected to a Buffalo wireless router configured for remote access, then it may be
turned on from outside the local network (from the WAN side). To use this feature, connect the router to only
LAN port 1 on the TeraStation.
• If you send a Wake-on-LAN packet to the current main TeraStation (originally the backup TeraStation) right
after it replaces the faulty TeraStation via failover, Wake-on-LAN may not work. In such a case, restart the
TeraStation once.
UPS (Uninterruptible Power Supply)
If a UPS (sold separately) is attached, the TeraStation can be automatically shut down for protecting data in the
event of a power outage.
1 Plug the power cable of the UPS to a wall socket.

different TeraStation is connected to the UPS, select "Sync with UPS connected to another TeraStation on the
same network". After making this selection, enter the IP address of the TeraStation that will be the sync source
in "Other TeraStation's IP Address".
• When the TeraStation is rebooted after an automatic shutdown (such as from a power outage or power
supply problem), verify that the power supply has been restored. If the TeraStation is turned on while it is
still running on the UPS and without the power supply restored, automatic shutdown is not performed, even
after the specified time has elapsed.
• If the power supply from the UPS to the TeraStation is stopped and restarted when UPS recovery is enabled,
the TeraStation is automatically restarted.
Port Trunking
Two Ethernet cables can be used to establish two separate communication routes providing LAN port redundancy
and improving communication reliability. The use of two Ethernet cables enables access to the TeraStation even if
one of the cables is disconnected.
The port trunking modes that can be set in the TeraStation are shown below.
Trunking Mode Characteristics
Round-robin*Network packets are transmitted in sequential order from the first
available NIC slave through the last.
Active-backup Only one NIC slave in the bond is active. A different slave becomes
active if and only if the active slave fails.
XOR*
Transmits network packets based on [(source MAC address XOR'd
with destination MAC address) modulo NIC slave count]. This
selects the same NIC slave for each destination MAC address.
Broadcast Transmits network packets on all slave network interfaces.
Dynamic link aggregation**
Creates aggregation groups that share the network speed and
duplex settings. Utilizes all slave network interfaces in the active
aggregator group according to the 802.3ad specification.
162
Trunking Mode Characteristics
TLB
The outgoing network packet traffic is distributed according to
the current load (relative to the speed) on each network interface
slave.
*A separate intelligent switch that supports EtherChannel or other port trunking is required. Configure two LAN
ports on the switch for port trunking first.
**A separate intelligent switch that supports IEEE 802.3ad is required. Configure LACP in the switch first.
Configuring Port Trunking
If the TeraStation is being used as an iSCSI hard drive, disable iSCSI before changing network settings such as port
trunking. Navigate to Drives - iSCSI in Settings and move the iSCSI switch to the position temporarily.
1 Use an Ethernet cable to connect the hub LAN port and TeraStation LAN port 1.

the mount point.
For Linux:
171
mount -t nfs 192.168.11.10:/mnt/array1/share /mnt/nas
For Windows Service for Unix 3.5:
mount 192.168.11.10:/mnt/array1/share z:
For Solaris 10:
mount -F nfs 192.168.11.10:/mnt/array1/share /mnt/nas
Notes:
• To configure access restrictions by IP address, click Services - Edit, then enter the desired settings.
• To use shared folders set for NFS as drives on VMware ESX/ESXi, change the operation mode from "User
Mode" (default setting) to "Kernel Mode" on the screen navigating to Services - Edit.
• If you configure "Guest Permission" to "Forced" on the screen navigating to Services - Edit, user ID and group
ID should be 99 when the data is written from NFS clients; this is recommended for SMB or other protocols as
well. Use "Ignored" if the TeraStation only enables NFS connection.
Encrypting Data Transmission
Encrypting Settings Data
All communication with Settings can use SSL encryption if you access settings through https://.
Encrypting FTP Transfer Data
You can encrypt passwords and files using SSL/TLS for secure FTP communication. First, open a shared folder's
settings and click Edit; under "LAN Protocol Support", check "FTP" and click OK. Enable SSL security in the setup
screen for your FTP client. The procedure depends on the FTP client software.
172
SSL Keys
SSL keys are used during setup screen operations and FTP communication. SSL (Secure Socket Layer) is a type of
encryption system called public key encryption. Generally, SSL is managed by the two files below.
server.crt (SSL Certificates)
The TeraStation sends the file to a computer, and the computer uses it to perform encryption. The TeraStation
receives the encrypted data and uses server.key (the private key) to decrypt the data.
In SSL, this key contains the server certificate, and depending on your computer environment, a check may be
performed to determine the trustworthiness of the certificate. The server certificate included in the TeraStation in
the default settings was created by Buffalo, and in some cases the message "There is a problem with this website's
security certificate" may be displayed in your browser or other software. Disregard this message and continue.
server.key (SSL Key)
This file is used as a pair with server.crt (server certificate). This is required for decrypting the data that was
encrypted by the server certificate, and this is normally not revealed.
Updating SSL Key
To update a server certificate and a private key for SSL, follow this procedure.
1 Navigate to Management - SSL.
2 Register "server.key" for "Secret Key" and "server.crt" for "Server Certificate (.crt)", then click Import.
Notes:
• Place the SSL key files (server.key, server.crt) directly below the C root drive. The SSL key may not be able to
be updated if it is placed in folders or paths that contain multi-byte characters.
• Use the provided password for the SSL key.
• If Settings cannot be displayed after updating, initialize the TeraStation settings.
• Updating the firmware initializes an SSL key.
