Chapter 5 Disk Manager
Disk Manager is an application that manages RAID arrays and internal or external drives. To open Disk Manager, click
the icon on the home screen.
RAID Modes
The LinkStation supports many types of RAID. The type of RAID arrays available for use depends on how many drives
are installed on your LinkStation.
RAID 1
Combines two drives into a mirrored array. The usable space is equal to the capacity of a single drive. Identical data
is written to each drive. If a drive becomes 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 two drives into a single array. The usable space is equal to the total capacity of all drives in the array.
This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array
becomes damaged, then all data in the array will be lost.
Linear
Combines all drives from drives into a single virtual drive. For this virtual drive, data will be written onto the first
drive, then to the next drive when the first drive becomes full, and so on. The usable space is equal to the total
capacity of all drives in the array. Linear mode offers no redundancy. If any of the drives become damaged, then all
data on that drive will be lost.
JBOD
This mode uses the drives inside the LinkStation as individual drives. The usable space is equal to the total capacity
of all drives on the LinkStation. If any of the drives become damaged, then all data on that drive will be lost.
Working with RAID Arrays
Note: 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.
Using JBOD
With JBOD, each drive on the LinkStation is addressed separately. To put drives from an array into JBOD, follow the
procedure below.
1 From Settings, click Disk Manager ( ).
36
Chapter 5 Disk Manager
2 Click the RAID tab.
3 Click the array to delete.
37
Chapter 5 Disk Manager
4 Click Delete.
5 Two different warnings will be displayed. Read them carefully and click Yes for both.
6 Format the drive by referring to the “Formatting Drives” section below.
Once JBOD is configured, the default shared folders will automatically be created only on the drive that is initially
formatted. Create a shared folder on the other drives by referring to the “Adding a Shared Folder” section in chapter
7.
Changing the RAID Mode
To change the RAID mode, first put the drives into JBOD by referring to the “Using JBOD” section above. Then, follow
the procedure below.
Note: You can also configure the RAID settings, including changing the RAID mode, using the initial setup wizard,
but you will lose all settings on the LinkStation.
To launch the initial setup wizard, initialize the LinkStation settings from System Settings > Reset, then follow the
procedure on the screen to finish changing the RAID mode.
1 From Settings, click Disk Manager ( ).
38
Chapter 5 Disk Manager
2 Click the RAID tab.
3 Click Create RAID Array.
39
Chapter 5 Disk Manager
4 Select a RAID mode and click Next.
5 Click Yes.
6 RAID array creation will start. Wait until it’s done.
7 Click OK, then Close when completed.
The new RAID array will be created. Next, create a shared folder by referring to the “Adding a Shared Folder” section
in chapter 7.
Expanding RAID Capacity Without Deleting Data
If the drives in your LinkStation are in a RAID 1 array with two drives or they are in degraded mode, you can expand
the RAID array capacity without erasing the data on the drives. To expand the capacity, you should have two new
drives with capacity larger than the remaining drive.
1 Shut down the LinkStation and remove one of the drives. Do not remove both drives at the same time.
2 Insert a new drive (with a larger capacity than the remaining drive) and turn on the LinkStation.
3 When the power LED glows white or blinks amber, press and hold the function button for five seconds.
4 The LinkStation will start rebuilding the RAID array. After a few minutes, the I18 message will be displayed in
NAS Navigator2. Wait until the drive finishes rebuilding; the I18 message will be extinguished.
5 After the RAID array is rebuilt, shut down the LinkStation again and remove another drive.
6 Insert another new drive and turn it on.
7 When the power LED blinks amber, press and hold the function button for five seconds.
8 The LinkStation will start rebuilding the RAID array again. Wait until the I18 message is extinguished as step 4
above.
9 After the I18 message disappears, open Settings and click Disk Manager ( ).
40
Chapter 5 Disk Manager
10 Click the RAID tab and the RAID array to make the capacity larger.
11 Click Expand.
12 Read the warning message carefully and click Yes.
13 The RAID array will be rebuilt and its capacity will expand. The power LED will blink amber and the I18 and
I46 messages will appear. Wait until those messages disappear and the power LED returns to a steady white.
Adding an External Drive
Your LinkStation features a USB port, and you can connect an external drive to this port. For external drives, Buffalo
USB drives are recommended. The following file systems for external drives are supported: ext2, ext3, ext4, FAT32,
exFAT, NTFS, HFS Plus
Make sure only one device is connected to a USB port on the LinkStation. Some external drives with automatic
power-on won’t turn on automatically when connected to the LinkStation. Use their manual power switch to turn
them on. Be sure to connect only one bus-powered drive at a time. If there is insufficient bus power for your USB
drive, connect its AC adapter.
41
Chapter 5 Disk Manager
Note: This LinkStation will not recognize USB drives that are larger than 16 TB. Use only USB drives that are 16 TB or
smaller.
Dismounting an External Drive
If the LinkStation is powered on, dismount an external drive before unplugging it. You may dismount the external
drive from Settings. If the LinkStation is off, then the external drive is already dismounted and may be unplugged
safely.
Dismounting Using the Eject Button
1 Click the icon at the upper right corner of the home screen toolbar.

from the backup destination folder. The backup destination folder will always remain the same size as the backup
source folder, and the folder structure in the backup destination will be the same as the backup source folder.
• Folders available as backup sources:
◦Shared folder on the backup source LinkStation
◦USB drive connected to the backup source LinkStation
◦Shared folder on another Buffalo NAS device
• Folders available as backup destinations:
◦Shared folder on the backup source LinkStation
◦USB drive connected to the backup source LinkStation
◦Shared folder on another Buffalo NAS device
Preparing a Backup Destination
Configure a shared folder on a Buffalo NAS device or connected USB drive as a backup destination. The following
procedure explains using another shared folder on the LS500 series LinkStations as a backup destination. The
procedure may vary depending on which Buffalo NAS device is selected as a destination.
1 From Settings, click System Settings ( ).

3 Choose the folder to set as a backup destination.
99
Chapter 8 System
4 Select the “Backup” checkbox for “LAN Protocols”.
5 Enter the desired characters into the backup device access key field and click OK.
Note: You may leave this field blank if you do not want a backup device access key, but for security reasons
we highly recommend entering one for the shared folder. If a backup device access key is configured for the
shared folder, that folder will not show up as a target for the backup source or destination when configuring a
backup job on another Buffalo NAS device unless it’s entered. You may create multiple folders using different
backup device access keys for backup, but only one access key can be used on the LinkStation. Folders that are
configured with a different access key cannot be used.
A backup destination has been created.
Configuring a Backup Job
You can configure backup jobs by using another shared folder on the Buffalo NAS device or a USB drive connected
to the LinkStation as a destination. You can also back up to a Buffalo NAS device on another network as long as the
two networks are connected by a VPN or the route is configured properly.
1 From Settings, click System Settings ( ).
