Note. Previous generations of Seagate Self-Encrypting Drive models were called Full Disk Encryption
(FDE) models before a differentiation between drive-based encryption and other forms of encryp-
tion was necessary.
Note. The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for
“Security of Data at Rest” based on the standards defined by the Trusted Computing Group (see
www.trustedcomputinggroup.org).
These drives provide the following key features:
• 7200 RPM spindle speed.
• High instantaneous (burst) data-transfer rates (up to 600MB/s).
• Perpendicular recording technology provides the drives with increased areal density.
• State-of-the-art cache and on-the-fly error-correction algorithms.
• Native Command Queueing with command ordering to increase performance in demanding applications.
• Full-track multiple-sector transfer capability without local processor intervention.
• Quiet operation.
• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
• Support for S.M.A.R.T. drive monitoring and reporting.
• Supports latching SATA cables and connectors.
• Worldwide Name (WWN) capability uniquely identifies the drive.

2.1
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 jump-
ers 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 you to install a Serial ATA host adapter and Serial ATA disc drive in your current
system and expect all of your existing applications to work as normal.
The Serial ATA interface connects each disc 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.
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.
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 regis-
ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi-
tional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 5 on page 26.
3.8.1 Power consumption
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on
an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient
temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating
speed.
• 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.
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.

Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems,
you can control power management 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 disc
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 disc access is necessary.
• Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buf-
fer 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 disc access is necessary.
3.8.4.1
Extended Power Conditions - PowerChoiceTM
Utilizing the load/unload architecture a programmable power management interface is provided to tailor sys-
tems for reduced power consumption and performance requirements.
The table below lists the supported power conditions available in PowerChoice. Power conditions are ordered
from highest power consumption (and shortest recovery time) to lowest power consumption (and longest
recovery time) as follows: Idle_a power >= Idle_b power >= Idle_c power >= Standby_z power. The further you
go down in the table, the more power savings is actualized. For example, Idle_b results in greater power sav-
ings than the Idle_a power condition. Standby results in the greatest power savings.

Each power condition has a set of current, saved and default settings. Default settings are not modifiable.
Default and saved settings persist across power-on resets. The current settings do not persist across power-on
resets. At the time of manufacture, the default, saved and current settings are in the Power Conditions log
match.
PowerChoice is invoked using one of two methods
• Automatic power transitions which are triggered by expiration of individual power condition timers. These
timer values may be customized and enabled using the Extended Power Conditions (EPC) feature set using
the standardized Set Features command interface.
• Immediate host commanded power transitions may be initiated using an EPC Set Features "Go to Power
Condition" subcommand to enter any supported power condition. Legacy power commands Standby Imme-
diate and Idle Immediate also provide a method to directly transition the drive into supported power condi-
tions.
PowerChoice exits power saving states under the following conditions
• Any command which requires the drive to enter the PM0: Active state (media access)
• Power on reset
PowerChoice provides the following reporting methods for tracking purposes
Check Power Mode Command
• Reports the current power state of the drive
Identify Device Command
• EPC Feature set supported flag
• EPC Feature enabled flag is set if at least one Idle power condition timer is enabled
Power Condition Log reports the following for each power condition
• Nominal recovery time from the power condition to active
• If the power condition is Supported, Changeable, and Savable
• Default enabled state, and timer value
• Saved enabled state, and timer value
• Current enabled state, and timer value

Environmental limits
Temperature and humidity values experienced by the drive must be such that condensation does not occur on
any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F
(14.8°C). Maximum wet bulb temperature is 82°F (28°C).
3.9.1
Temperature
a. Operating
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°C) drive case temperature
range with a maximum temperature gradient of 36°F (20°C) per hour.
The maximum allowable drive case temperature is 60°C.
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal
case temperature. The rated MTBF is based upon a sustained case temperature of 104°F (40°C). Occa-
sional excursions in operating temperature between the rated MTBF temperature and the maximum drive
operating case temperature may occur without impact to the rated MTBF temperature. However continual
or sustained operation at case temperatures beyond the rated MTBF temperature will degrade the drive
MTBF and reduce product reliability.
Air flow may be required to achieve consistent nominal case temperature values (see Section 4.5). To con-
firm that the required cooling is provided for the electronics and HDA, place the drive in its final mechanical
configuration, and perform random write/read operations. After the temperatures stabilize, measure the
case temperature of the drive.
b. Non-operating
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This
specification assumes that the drive is packaged in the shipping container designed by Seagate for use with
drive.

Acoustics
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea-
surements are consistent with ISO document 7779. Sound power measurements are taken under essentially
free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.
Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined
by the following equation:
(Number of seeks per second = 0.4 / (average latency + average access time)

The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-
800-468-3472. You can also determine remaining warranty using the Seagate web site (www.seagate.com).
The drive serial number is required to determine remaining warranty information.
Shipping
When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Sea-
gate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in a
non-approved container voids the drive warranty.
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in tran-
sit. Contact your authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping
by an air-ride carrier experienced in handling computer equipment.
Storage
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives
should be stored in the original unopened Seagate shipping packaging whenever possible. Once the drive is
removed from the Seagate original packaging the recommended maximum period between drive operation
cycles is 30 days. During any storage period the drive non-operational temperature, humidity, wet bulb, atmo-
spheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.
Product repair and return information
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does
not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids
the warranty.

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, chlo-
ride, 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 vulca-
nized 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
This section contains the specifications and instructions for configuring and mounting the drive.
4.1
Handling and static-discharge precautions
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis-
charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:
Caution:
• 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 you mount 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.
Constellation.2 Serial ATA Product Manual, Rev. B
25
4.2
Configuring the drive
Each drive on the Serial ATA interface connects point-to-point with the Serial ATA host adapter. There is no
master/slave relationship because each drive is considered a master in a point-to-point relationship. 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.
Serial ATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive
for proper operation; however, if you connect the drive and receive a “drive not detected” error, your SATA-
equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation.
4.3
Serial ATA cables and connectors
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-
tions. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37in). See Table 5 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, you can connect the drive as illustrated in Figure 5.

4.4
Drive mounting
You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the
bottom-mounting holes. See Figure 6 for drive mounting dimensions. Follow these important mounting precau-
tions when mounting the drive:
• Allow a minimum clearance of 0.030 in (0.76 mm) around the entire perimeter of the drive for cooling as a
• Use only M3 x 0.5 metric mounting screws.
• Four (4) threads (0.080 in) minimum screw engagement recommended. Also ensure maximum screw length
does not bottom out in mounting holes.
• Do not overtighten the mounting screws (maximum torque: 4.5 in-lb, ± 0.45 in-lb).

4.5
Cooling
Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding
The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and
head and disc assembly (HDA). You should confirm that adequate heat removal is provided using the temper-
ature measurement guidelines described in Section 3.9.1.
Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 3.9.1
in which case the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is
created while providing air flow to the electronics and HDA. Also, the shortest possible path between the air
inlet and exit should be chosen to minimize the travel length of air heated by the drive and other heat sources
within the rack, cabinet, or drawer environment.
If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 7. The air-flow pat-
terns are created by one or more fans, either forcing or drawing air as shown in the illustrations. Conduction,
convection, or other forced air-flow patterns are acceptable as long as the temperature measurement guide-

About FIPS
The Federal Information Processing Standard (FIPS) Publication 140-2, FIPS PUB 140-2, is a U.S. govern-
ment 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 coordi-
nate the requirements and standards for cryptography modules that include both hardware and software com-
ponents.
Federal Information Processing Standard (FIPS) 140-2 Level 2 Certification requires drives to go through gov-
ernment agencies certifications to add requirements for physical tamper-evidence and role-based authentica-
tion.
Level 2 security
Level 2 improves upon the physical security mechanisms of a Level 1 (lowest level of security) cryptographic
module by requiring features that show evidence of tampering, including tamper-evident coatings or seals that
must be broken to attain physical access to the plaintext cryptographic keys and critical security parameters
(CSPs) within the module, or pick-resistant locks on covers or doors to protect against unauthorized physical
access.

About self-encrypting drives
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, com-
monly known as “protection of data at rest.” These drives are compliant with the Trusted Computing Group
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the com-
puter, storage and digital communications industry. Seagate’s SED models comply with the standards pub-
lished by the TCG.
To use the security features in the drive, the host must be capable of constructing and issuing the following two
commands:
• Security Protocol Out
• Security Protocol In
These commands are used to convey the TCG protocol to and from the drive in their command payloads.
6.1
Data encryption
Encrypting drives use one inline encryption engine for each port, 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 engines are always in operation, cannot be disabled, and do not detract
in any way from the performance of the drive.
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
6.2
Controlled access
The drive has two security partitions (SPs) called the "Admin SP" and the "Locking SP." These act as gate-
keepers 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.
6.2.1
Admin SP
The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 6.4).
Access to the Admin SP is available using the SID (Secure ID) password or the MSID (Makers Secure ID)
password.
30
Constellation.2 Serial ATA Product Manual, Rev. B
6.2.2
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 BandMasterX or EraseMaster passwords. Since the drive owner can define
up to 16 data bands on the drive, each data band has its own password called BandMasterX where X is the
number of the data band (0 through 15).
6.2.3
Default password
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random
value is printed on the drive label and it can be read by the host electronically over the I/O. 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.
6.3
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 pro-
vide random numbers to the host for system use, including using these numbers as Authentication Keys (pass-
words) for the drive’s Admin and Locking SPs.
6.4
Drive locking
In addition to changing the passwords, as described in Section 6.2.3, 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. 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.
When the drive is shipped from the factory, the firmware download port is locked and the drive will reject any
attempt to download new firmware. The drive owner must use the SID credential to unlock the firmware down-
load port before firmware updates will be accepted.
6.5
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 Band) which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a
start LBA and an LBA range. The real estate for this band is taken from the Global Band. An additional 14 Data
Bands may be defined in a similar way (Band2 through Band15) but before these bands can be allocated LBA
space, they must first be individually enabled using the EraseMaster password.
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 and its own user-supplied password. The host may
change the Encryption Key (see Section 6.6) or the password when required. The bands should be aligned to
4K LBA boundaries.
Constellation.2 Serial ATA Product Manual, Rev. B
31
6.6
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 will 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 tanta-
mount to an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.
6.7
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.
6.8
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 3.8 for power
requirements on the standard (non-SED) drive models.
6.9
Supported commands
The SED models support the following two commands in addition to the commands supported by the standard
• Security Protocol Out (B5h)
• Security Protocol In (A2h)
6.10
RevertSP
The SED models will support RevertSP feature where it 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.

Set Features command
This command controls the implementation of various features that the drive supports. When the drive receives
this command, it sets BSY, checks the contents of the Features register, clears BSY and generates an inter-
rupt. If the value in the register does not represent a feature that the drive supports, the command is aborted.
Power-on default has the read look-ahead and write caching features enabled. The acceptable values for the
Features register are defined as follows:

S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive moni-
tors predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines
that a failure is likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable.
S.M.A.R.T. predictability is limited to the attributes the drive can monitor. For more information on S.M.A.R.T.
commands and implementation, see the Draft ATA-5 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 ) that elimi-
H
nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
This drive is shipped with S.M.A.R.T. features disabled. You must have a recent BIOS or software package that
supports S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the
drive uses.
