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

• High instantaneous (burst) data-transfer rates (up to 600MB per second).

• Native Command Queuing with command ordering to increase performance in demanding applications.

• Perpendicular recording technology provides the drives with increased areal density.

• PowerChoice™ for selectable power savings

• SeaTools™ diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

• State-of-the-art cache and on-the-fly error-correction algorithms.

• Support for S.M.A.R.T. drive monitoring and reporting.

• Supports latching SATA cables and connectors.

• Tarnish-resistant components to help protect drive from environmental elements, increasing field reliability.

• Worldwide Name (WWN) capability uniquely identifies the drive.

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: High Speed Serialized AT Attachment” specification. The specification can be downloaded from

www.serialata.org.

Note Seagate recommends validating the configuration with the selected HBA/

RAID controller manufacturer to ensure use of full capacity is supported.

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.

2.5.6 Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 V line or an

equivalent 15-ohm resistive load on the +5V line.

• Using 12V power, the drive is expected to operate with a maximum of 120mV peak-to-peak square-wave injected noise at up to

10MHz.

• Using 5V power, the drive is expected to operate with a maximum of 100mV peak-to-peak square-wave injected noise at up to

10MHz.

2.5.8 Extended Power Conditions - PowerChoice™

Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems 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 users go down in the table, the more power savings is actualized. For

example, Idle_b results in greater power savings 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 Immediate and Idle Immediate also provide a

method to directly transition the drive into supported power conditions.

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

Note Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

PowerChoice Manufacture Default Power Condition Timer Values

Default power condition timer values have been established to assure product reliability and data integrity. A minimum timer value

threshold of two minutes ensures the appropriate amount of background drive maintenance activities occur. Attempting to set a

timer values less than the specified minimum timer value threshold will result in an aborted EPC "Set Power Condition Timer"

subcommand.

Setting power condition timer values less than the manufacturer specified defaults or issuing the EPC "Go to Power Condition"

subcommand at a rate exceeding the default timers may limit this products reliability and data integrity.

Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements 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.

)

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

2.9 Test for Prominent Discrete Tones (PDTs)

Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is the use of the

absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern tone audibility and to compensate

for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards.

2.10 Electromagnetic immunity

When properly installed in a representative host system, the drive operates without errors or degradation in performance when

subjected to the radio frequency (RF) environments defined in the following table:

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

2.11 Reliability

2.11.1 Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)

The production disk drive shall achieve an annualized failure-rate of 0.44% (MTBF of 2,000,000 hours) over a 5 year service life when

used in Enterprise Storage field conditions as limited by the following:

• 8760 power-on hours per year.

• HDA temperature as reported by the drive <= 40°C

• Ambient wet bulb temp <= 26°C

• Typical workload

• The AFR (MTBF) is a population statistic not relevant to individual units

• ANSI/ISA S71.04-2013 G2 classification levels and dust contamination to ISO 14644-1 Class 8 standards (as measured at the device)

The MTBF specification for the drive assumes the operating environment is designed to maintain nominal drive temperature and

humidity. Occasional excursions in operating conditions between the rated MTBF conditions and the maximum drive operating

conditions may occur without significant impact to the rated MTBF. However continual or sustained operation beyond the rated

MTBF conditions will degrade the drive MTBF and reduce product reliability.

2.12 Agency and Safety Certifications

Each Hard Drive and Solid State Drive ("drives") has a product label that includes certifications that are applicable to that specific

drive. The following information provides an overview of requirements that may be applicable to the drive.

2.12.1 Safety certification

The drives are recognized in accordance with UL/cUL 60950-1 and EN 60950-1.

The security features of Self-Encrypting Drive models are based on the “TCG Storage Architecture Core Specification” and the “TCG

Storage Workgroup Security Subsystem Class: Enterprise_A” specification with additional vendor-unique features as noted in this

product manual.

2.12.2 Regulatory Models

The following regulatory model number represent all features and configurations within the series:

Regulatory Model Numbers: STL010

Nonrecoverable read errors 1 per 1015 bits read, max

2.13.3 Taiwan Requirements — Taiwan RoHS

Taiwan RoHS refers to the Taiwan Bureau of Standards, Metrology and Inspection’s (BSMI) requirements in standard CNS 15663,

Guidance to reduction of the restricted chemical substances in electrical and electronic equipment. Seagate products must comply

with the “Marking of presence” requirements in Section 5 of CNS 15663, effective January 1, 2018. This product is Taiwan RoHS

compliant.

The following table meets the Section 5 “Marking of presence” requirements.

2.13 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 hard disk drives are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the

most damaging. 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.

Seagate recommends that data centers be kept clean by monitoring and controlling the dust and gaseous contamination. Gaseous

contamination should be within ANSI/ISA S71.04-2013 G2 classification levels (as measured on copper and silver coupons), and dust

contamination to ISO 14644-1 Class 8 standards, and MTBF rated conditions as defined in the Annualized Failure Rate (AFR) and

Mean Time Between Failure (MTBF) section.

The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. Users 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 the original box. Seagate 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 transit. Contact the

authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced in

handling computer equipment.

Storage

Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged within the

defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year packaged or

unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and non-corrosive

environment). During any storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions, shock,

vibration, magnetic and electrical field specifications should be followed.

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.

Seagate Exos 7E8 SATA Product Manual, Rev. B 27

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 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.

3.3 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).

See Table 13 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 illustrated in Figure 5.

Figure 5. Attaching SATA cabling

Each cable is keyed to ensure correct orientation. Exos 7E8 SATA drives support latching SATA connectors.

Caution

• Before handling the drive, put on a grounded wrist strap, or ground oneself 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.

Seagate Exos 7E8 SATA Product Manual, Rev. B 28

3.4 Drive mounting

Users 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 precautions when mounting the drive:

• Allow a minimum clearance of 0.030 in (0.76mm) around the entire perimeter of the drive for cooling.

• Use only 6-32 UNC mounting screws.

• The screws should be inserted no more than 0.140 in (3.56mm) into the bottom or side mounting holes.

• Do not overtighten the mounting screws (maximum torque: 6 in-lb).

4.0 About 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) Enterprise Storage Specifications as

detailed in Section 2.14.

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 ATA commands:

•Trusted Send

•Trusted Receive

These commands are used to convey the TCG protocol to and from the drive in their command payloads.

4.1 Data encryption

Encrypting drives use one inline encryption engine for each port, employing AES-256 bit data encryption in AES-XTS 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 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 7.5).

4.2 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.

4.2.1 Admin SP

The Admin SP allows the drive's owner to enable or disable firmware download operations (see Section 4.4). Access to the Admin SP

is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.

4.2.2 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).

4.2.3 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.

Seagate Exos 7E8 SATA Product Manual, Rev. B 31

4.3 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.

4.4 Drive locking

In addition to changing the passwords, as described in Section 4.2.3, 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. 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.

When the drive is shipped from the factory, the firmware download port is unlocked.

4.5 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 30 Data Bands may be defined in a similar way (Band2 through Band31) 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 4.6) or the password when required. The bands should be aligned to 4K LBA boundaries.

4.6 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 tantamount to an instantaneous data erase and is very useful if the drive is to be scrapped or

redispositioned.

4.7 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.

Seagate Exos 7E8 SATA Product Manual, Rev. B 32

4.8 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 2.5 for power requirements on the standard (non-SED) drive models.

4.9 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 14:

• Trusted Send (5Eh) or Trusted Send DMA (5Fh)

• Trusted Receive (5Ch) or Trusted Receive DMA (5D)

4.10 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.

4.11 ATA Security Erase Unit Command on SED SATA drives

The ATA SECURITY ERASE UNIT command shall support both the Normal and Enhanced erase modes with the following

modifications/additions:

• Normal Erase: Normal erase shall be accomplished by changing the media encryption key for the drive followed by an overwrite

operation that repeatedly writes a single sector containing random data to the entire drive. The write operation shall bypass the

media encryption. On reading back the overwritten sectors, the host will receive a decrypted version, using the new encryption

key, of the random data sector (the returned data will not match what was written).

• Enhanced Erase: Enhanced erase shall be accomplished by changing the media encryption key for the drive.

4.12 Sanitize Device - CRYPTO SCRAMBLE EXT

This command cryptographically erases all user data on the drive by destroying the current data encryption key and replacing it with

a new data encryption key randomly generated by the drive. Sanitize Device is a command field B4h and Feature field 0011h

(CRYPTO SCRAMBLE EXT).

The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS ACS-2 with the exceptions and/or modifications described

in this section.

The drive shall not support the OVERWRITE EXT and BLOCK ERASE EXT sub-commands.

Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a customer-specific basis. OEM drives shall support the

command.

5.0 About FIPS

The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security Standard used to

accredit cryptographic modules. It is titled 'Security Requirements for Cryptographic Modules (FIPS PUB 140-2)' and is issued by the

National Institute of Standards and Technology (NIST).

Purpose

This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a security system

protecting sensitive but unclassified information. The standard provides four increasing, qualitative levels of security: Level 1, Level 2,

Level 3 and Level 4. These levels are intended to cover the wide range of potential applications and environments in which

cryptographic modules may be employed.

Seagate Enterprise SEDs

The SEDs referenced in this Product Manual have been validated by CMVP and have been thoroughly tested by a NVLAP accredited

lab to satisfy FIPS 140-2 Level 2 requirements. In order to operate in FIPS Approved Mode of Operation, these SEDs require security

initialization. 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".

Level 2 security

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 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

6.0 Serial ATA (SATA) interface

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.

For detailed information about the Serial ATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment” specification.

6.1 Hot-Plug compatibility

Exos 7E8 SATA drives incorporate connectors which enable users to hot plug these drives in accordance with the Serial ATA Revision

3.2 specification. This specification can be downloaded from www.serialata.org.

6.2 Serial ATA device plug connector pin definitions

Table 13 summarizes the signals on the Serial ATA interface and power connectors.

Notes:

1. All pins are in a single row, with a 1.27mm (0.050”) pitch.

2. The comments on the mating sequence apply to the case of backplane blindmate connector only. In this case, the mating sequences are:

• the ground pins P4 and P12.

• the pre-charge power pins and the other ground pins.

• the signal pins and the rest of the power pins.

3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane config-

uration.

4. All used voltage pins (Vx) must be terminated.

Caution The drive motor must come to a complete stop (Ready to spindle stop time indicated in Section 2.4)

prior to changing the plane of operation. This time is required to insure data integrity.

6.3.2 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 interrupt. 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

6.3.3 S.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 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates unnecessary drive

returns. The diagnostic software ships with all new drives and is also available at:

http://www.seagate.com/support/downloads/seatools/.

This drive is shipped with S.M.A.R.T. features disabled. Users 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.
