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 different
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. Department of Commerce, Bureau of Industry and Security (for
more information, visit www.bis.doc.gov), and controlled for import and use outside of the U.S. Seagate reserves the right to change, without notice, product offerings or specifications.

1.1About 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 host adapter may, optionally, emulate a master/slave environment to host software where two devices on separate Serial ATA ports
Note
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 3.2). The specification can be downloaded from www.serialata.or
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.

• Active mode
The drive is in Active mode during the read/write and seek operations.
n Idle mode
The electronics remains powered, and the drive accepts all commands and returns to Active mode when disk access is necessary.
• Standby mode
The drive enters Standby mode immediately 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 electronics are in low power mode, the heads are parked and the spindle is at rest. The
drive accepts all commands and returns to Active mode when disk access is necessary.
n Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the electronics are in low power mode, 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.
n 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.

2.11.1 Data loss under power interruption with write cache enabled
Drive preserves its data during all operations except in cases where power to the drive is interrupted during write operations. This could result in
either an uncorrected data error being reported, or the entire sector/track becoming unreadable. This can be permanently recovered by rewriting
to the same location on the drive. Additionally any data present in the DRAM buffer will not be written to the disk media, additionally, the drive will
not be able to return the original data.
In order to prevent this data loss, the host should issue a standby immediate or flush cache command before a controlled power off operation to the
drive.

2.14Corrosive 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.

3.0Configuring and Mounting the Drive
Power cable
Signal cable
Signal connector
Power connector
This section contains the specifications and instructions for configuring and mounting the drive.
3.1Handling 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.
• 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.
CAUTION
3.2Configuring 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.
• 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.
3.2.1Serial 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 Tabl e 11 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 3.
Figure 3Attaching SATA Cabling
Each cable is keyed to ensure correct orientation. BarraCuda drives support latching SATA connectors.

About FIPS
4.0About 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.
Security Level 2.
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the requirement for tamperevidence, 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 6 on page 24) 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
5.0About (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 Trusted 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.
5.1Data 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).
5.2Controlled 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.
5.2.1Admin 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.
5.2.2Locking 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.
5.2.3Default 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.
5.2.4ATA Enhanced Security
The drive can utilize the system's BIOS through the ATA Security API for cases that do not require password management and additional security
policies.
Furthermore, the drive's ATA Security Erase Unit command shall support both Normal and Enhanced Erase modes with the following 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 BarraCuda Product Manual, Rev. D 25
About (SED) Self-Encrypting
5.3Random 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.
5.4Drive 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.
5.5Data 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 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.
5.6Cryptographic 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 tantamount to
an instantaneous data erase and is very useful if the drive is to be scrapped or redispositioned.
5.7Authenticated 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.
5.8Power 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.
5.9Supported Commands
The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed
in Tab le 1 2:
•Trusted Send
•Trusted Receive
5.10RevertSP
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.

Serial ATA (SATA) Interface
6.0Se rial ATA (S ATA) I nte rface
These drives use the industry-standard Serial ATA interface that supports FIS data transfers. It supports ATA programmed input/output (PIO) modes
0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–6. The drive also supports the use of the IORDY signal to provide reliable high-speed data
transfers.
For detailed information about the Serial ATA interface, refer to the Serial ATA: High Speed Serialized AT Attachment specification.
6.1Hot-Plug Compatibility
BarraCuda drives incorporate connectors which enable users to hot plug these drives in accordance with the Serial ATA: High Speed Serialized AT
Attachment specification revision 2.0. This specification can be downloaded from www.serialata.org. This device requires a COMRESET from the
host after a hotplug event.

6.3.3S.M.A.R.T. commands
S.M.A.R.T. provides near-term failure prediction for disk drives. When S.M.A.R.T. is enabled, the drive monitors 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 St and ard.
