When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your
computer’s operating system may use a dif ferent standard of measurement and report a lower capacity. In addition, some of the listed
capacity is used for formatting and other functions, and thus will not be available for data storage. Actual quantities will vary based on
various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating
environment and other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S.

SEAGATE LAPTOP THIN HDD PRODUCT MANUAL, REV. K 3
1.1 About the Serial ATA Interface
The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include:
Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers or other configuration
options.
Thinner and more flexible cabling for improved enclosure airflow and ease of installation.
Scalability to higher performance levels.
In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial ATA was designed to allow
users to install a Serial ATA host adapter and Serial ATA disk drive in the current system and expect all of the existing applications to work
as normal.
The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter. There is no master/
slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached on one Serial ATA host adapter, the host
operating system views the two devices as if they were both “masters” on two separate ports. This essentially means both drives behave
as if they are Device 0 (master) devices.
The Serial ATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward compatibility with
existing host systems and software. The Command and Control Block registers, PIO and DMA data transfers, resets, and interrupts are all
emulated.
The Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the
Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For additional information about how Serial ATA emulates
parallel ATA, refer to the Serial ATA International Organization: Serial ATA (Revision 2.6). The specification can be downloaded from
www.serialata.org.
NOTE
The host adapter may, optionally, emulate a master/slave environment to host software where two devices
on separate Serial ATA ports are represented to host software as a Device 0 (master) and Device 1 (slave)
accessed at the same set of host bus addresses. A host adapter that emulates a master/slave environment
manages two sets of shadow registers. This is not a typical Serial ATA environment.

Rated workload
Average rate of <55TB/year. The MTBF specification for the drive assumes the I/O workload
does not exceed the average annualized workload rate limit of 55TB/year. Workloads
exceeding the annualized rate may degrade the drive MTBF and impact product reliability.
The average annualized workload rate limit is in units of TB per year, or TB per 8760 power-
on hours. Workload rate limit = TB transferred × (8760/recorded power-on hours).

2.5 Seek time
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The
specifications in the table below are defined as follows:
Track-to-track seek time is an average of all possible single-track seeks in both directions.
Average seek time is a true statistical random average of at least 5000 measurements of seeks between random tracks, less overhead.
2.6 Start/stop times

Power-on to ready (sec) 3.0 4.0
Power-on to ready (sec) (SED models) 3.5 4.5
Standby to ready (sec) 2.5 3.0
2.7 Power Specifications
The drive receives DC power (+5V) through a native SATA power connector (refer to Figure 2).
2.7.1 Power consumption
Power requirements for the drives are listed in the table in Table 4. Typical power measurements are based on an average of drives
tested, under nominal conditions, at 25°C ambient temperature. These power measurements are done with Interface Power
Management modes like HIPM and DIPM enabled.
Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
Seek mode
During seek mode, the read/write actuator arm moves toward a specific position on the disk surface and does not execute a read or
write operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100 ms.
This mode is not typical.
Read/write power and current
Read/write power is measured with the heads on track, based on three 63 sector read or write operations every 100 ms.
Idle mode power
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.
Standby mode
During standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics are in
power-down mode.
Table 2 Typical seek times
Typical seek times (ms) Read
Track-to-track 1.5
Average 12.0
Average latency 5.6
NOTE
These drives are designed to consistently meet the seek times represented in this manual. Physical
seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted values.
However, due to the manner in which these drives are formatted, benchmark tests that include
command overhead or measure logical seeks may produce results that vary from these specifications.

2.7.2 Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line.
Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 20
MHz.
NOTE Equivalent resistance is calculated by dividing the nominal
voltage by the typical RMS read/write current.
2.7.3 Voltage tolerance
Voltage tolerance (including noise):
+5V ± 5%
2.7.4 Power management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, power management is
controlled through the system setup program. The drive features the following power-management modes:
Active mode
The drive is in active mode during the read/write and seek operations.
Idle mode
The buffer remains enabled, and the drive accepts all commands and returns to active mode any time disk access is necessary.
Standby mode
The drive enters standby mode when the host sends a standby Immediate command. If the host has set the standby timer, the drive can
also enter standby mode automatically after the drive has been inactive for a specifiable length of time. The standby timer delay is
established using a standby or idle command. In standby mode, the drive buffer is enabled, the heads are parked and the spindle is at
rest. The drive accepts all commands and returns to active mode any time disk access is necessary.
Sleep mode
The drive enters sleep mode after receiving a sleep command from the host. In sleep mode, the drive buffer is disabled, the heads are
parked and the spindle is at rest. The drive leaves sleep mode after it receives a hard reset or soft reset from the host. After receiving a
reset, the drive exits sleep mode and enters standby mode with all current translation parameters intact.
Idle and standby timers
Each time the drive performs an active function (read, write or seek), the standby timer is reinitialized and begins counting down from its
specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive makes a transition to
standby mode. In both Idle and standby mode, the drive accepts all commands and returns to active mode when disk access is
necessary.

2.14 Corrosive Environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments
containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate
every potential application environment.
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic
drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate
products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In
addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA)
or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can
outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing
materials near circuitry with sulfide-free alternatives.

CONFIGURING AND MOUNTING THE DRIVE
3.0 Configuring and Mounting the Drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1 Handling and Static-Discharge Precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
Observe the following standard handling and static-discharge precautions.
3.2 Configuring the Drive
Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave
relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one Serial ATA host
adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if
they are Device 0 (master) devices.
3.2.1 Serial ATA Cables and Connectors
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be
30 to 26 AWG with a maximum length of one meter (39.37 in). Refer to Table 8 for connector pin definitions. Either end of the SATA signal
cable can be attached to the drive or host.
For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle
incorporate features that enable the direct connection to be hot pluggable and blind mateable. For installations which require cables, users
can connect the drive as shown in Figure 2.
Figure 2 Attaching SATA Cabling
Each cable is keyed to ensure correct orientation. Laptop Thin HDD drives support latching SATA connectors.
CAUTION
• Keep the drive in the electrostatic discharge (ESD) bag until ready for installation to limit the
drive’s exposure to ESD.
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by
touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a
grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame only.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounting it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels.
Removal voids the warranty. Some factory-installed labels contain information needed to
service the drive. Other labels are used to seal out dirt and contamination.

ABOUT FIPS
4.0 About FIPS
The Federal Information Processing Standard (FIPS) Publication 140-2, FIPS PUB 140-2, is a U.S. government computer security
standard used to accredit cryptographic modules. It is titled “Security Requirements for Cryptographic Modules”. The initial publication was
on May 25, 2001 and was last updated December 3, 2002.
Purpose.
The National Institute of Standards and Technology (NIST) issued the FIPS 140 Publication Series to coordinate the requirements and
standards for cryptography modules that include both hardware and software components.
Federal Information Processing Standard (FIPS) 140-2 Level 2 Certification requires drives to go through government agencies
certifications to add requirements for physical tamper-evidence and role-based authentication. For more information, refer to 'Security
Rules' section in the 'Security Policy' document uploaded on the NIST website. To reference the product certification visit:
http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/1401vend.htm, and search for “Seagate”.
Security Level 2.
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the requirement for
tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the module. Tamper-evident coatings
or seals are placed on a cryptographic module so that the coating or seal must be broken to attain physical access to the critical security
parameters (CSP) within the module. Tamper-evident seals (example shown in Figure 5, page 19) are placed on covers to protect against
unauthorized physical access. In addition Security Level 2 requires, at a minimum, role-based authentication in which a cryptographic
module authenticates the authorization of an operator to assume a specific role and perform a corresponding set of services.

ABOUT (SED) SELF-ENCRYPTING DRIVES
5.0 About (SED) Self-Encrypting Drives
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as "protection of
data at rest." These drives are compliant with the T rusted Computing Group (TCG) Opal Storage Specifications as detailed in the following:
Trusted Computing Group (TCG) Documents (apply to Self-Encrypting Drive models only)
TCG Storage Architecture Core Specification, Version 2.0
TCG Storage Security Subsystem Class Opal Specification, Version 2.0
(see www.trustedcomputinggroup.org)
In case of conflict between this document and any referenced document, this document takes precedence.
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital
communications industry. Seagate's SED models comply with the standards published by the TCG.
To use the security features in the drive, the host must be capable of constructing and issuing the following two SATA commands:
Trusted Send
Trusted Receive
These commands are used to convey the TCG protocol to and from the drive in their command payloads.
5.1 Data Encryption
Encrypting drives use one inline encryption engine for each drive employing AES-256 data encryption in Cipher Block Chaining (CBC)
mode to encrypt all data prior to being written on the media and to decrypt all data as it is read from the media. The encryption engine is
always in operation and cannot be disabled.
The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never leaves the drive, and is inaccessible to
the host system. The DEK is itself encrypted when it is stored on the media and when it is in volatile temporary storage (DRAM) external to
the encryption engine. A unique data encryption key is used for each of the drive's possible16 data bands (see Section 5.5, Data Bands).
5.2 Controlled Access
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP." These act as gatekeepers to the drive security
services. Security-related commands will not be accepted unless they also supply the correct credentials to prove the requester is
authorized to perform the command.
5.2.1 Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 5.4, Drive Locking). Access to the
Admin SP is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.
5.2.2 Locking SP
The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is available using
the Admin or User passwords.
5.2.3 Default password
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only be read by the
host electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the default MSID password as the
authority to change all other passwords to unique owner-specified values.
5.2.4 ATA Enhanced Security
The drive can utilize the system's BIOS through the ATA Security API for cases that do not require password management and addi tional
security policies.

modifications/additions:
Normal Erase: Normal erase feature shall be performed by changing the Data Encryption Key (DEK) of the drive, followed by an overwrite
operation that repeatedly writes a single sector containing random data to the entire drive. This write operation bypasses the media
encryption. On reading back the overwritten sectors, the host will receive a decrypted version, using the new DEK of the random data
sector (the returned data will not match what was written).
Enhanced Erase: Enhanced erase shall be performed by changing the Data Encryption Key of the drive.
SEAGATE LAPTOP THIN HDD PRODUCT MANUAL, REV. K 21
ABOUT (SED) SELF-ENCRYPTING DRIVES
5.3 Random Number Generator (RNG)
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random numbers to the
host for system use, including using these numbers as Authentication Keys (passwords) for the drive's Admin and Locking SPs.
5.4 Drive Locking
In addition to changing the passwords, as described in Section 5.2.3, Default password, the owner should also set the data access controls
for the individual bands.
The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. In addition
"ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands "LockOnReset" setting of
"PowerCycle" to actually lock access to the band when a "PowerCycle" event occurs. This scenario occurs if the drive is removed from its
cabinet. The drive will not honor any data read or write requests until the bands have been unlocked. This prevents the user data from
being accessed without the appropriate credentials when the drive has been removed from its cabinet and installed in another system.
5.5 Data Bands
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data Ban d) which
comprises LBA 0 through LBA max. The host may allocate additional bands (Band1 to Band15) by specifying a start LBA and an LBA
range. The real estate for this band is taken from the Global Band.
Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).
Each data band has its own drive-generated encryption key. The host may change the Encryption Key (see Section 5.6, Cryptographic
Erase) or the password when required. The bands should be aligned to 4K LBA boundaries.
5.6 Cryptographic Erase
A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change the data
encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one key and wil l be read
using a different key. Since the drive overwrites the old key with the new one, and keeps no history of key changes, the user data can
never be recovered. This is tantamount to an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.
5.7 Authenticated Firmware Download
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files
which have been cryptographically signed by the appropriate Seagate Design Center.
Three conditions must be met before the drive will allow the download operation:
1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.
2. The download file must be signed and authenticated.
3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to the
correct drive model, and have compatible revision and customer status.
5.8 Power Requirements
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive
controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about
30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply. See the
tables in Section 2.7, Power Specifications for power requirements on the standard (non-SED) drive models.
5.9 Supported Commands
The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed
in Table 9:
Trusted Send
Trusted Receive
5.10 RevertSP
SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all SPs (Security
Providers) on the device to their original factory state. In order to execute the RevertSP method the unique PSID (Physical Secure ID)
printed on the drive label must be provided. PSID is not electronically accessible and can only be manually read from the drive label or
scanned in via the 2D barcode.
