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
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.

2.5.4 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
+5v = 250 mV pp from 100 Hz to 20 MHz.
+12v = 800 mV pp from 100 Hz to 8 KHz.

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.

2.6 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).
2.6.1 Temperature
a. Operating
41°F to 140°F (5°C to 60°C) temperature range with a maximum temperature gradient of 36°F (20°C) per hour as reported by the
drive.
The maximum allowable drive reported temperature is 140°F (60°C).
Air flow may be required to achieve consistent nominal drive temperature values (see Section 3.4). To confirm 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, monitor the current drive temperature using the SMART temperature attribute
194 or Device Statistics log 04h page 5.
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.
2.6.2 Humidity
The values below assume that no condensation on the drive occurs. Maximum wet bulb temperature is 84.2°F (29°C).
2.6.2.1 Relative humidity
2.6.3 Effective Altitude (sea level)
2.7 Shock and Vibration
Shock and vibration measurements specified in this document are made directly on the drive itself and applied in the X, Y, and Z axis at the drive
mounting point locations.
2.7.1 Shock
a. Operating
The drive will operate without error while subjected to intermittent shock pulses not exceeding 70 Gs (read) and 40 Gs (write) at
a duration of 2ms.
b. Non-operating
The drive will operate without non-recoverable errors after being subjected to shock pulses not exceeding 300g at a duration of
2ms.
2.7.2 Vibration
a. Linear Random Operating Vibration
The drive will operate without non-recoverable errors while being subjected to the random power spectral density noise
specified below.
Note
To maintain optimal performance drives should be run at nominal drive temperatures and humidity.
See Section 2.11, "Reliability" for rated MTBF device operating condition requirements.
Operating: 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Non-operating: 5% to 95% non-condensing relative humidity with a maximum gradient of 20% per hour.
Operating: –304.8 m to 3048 m (–1000 ft. to 10,000+ ft.)
Non-operating: –304.8 m to 12,192 m (–1000 ft. to 40,000+ ft.)
Seagate Exos 7E8 SATA Product Manual, Rev. F 19
b. Random Rotary Operating Vibration
The drive will exhibit greater than 90% throughput for sequential and random write operations while subjected to the shaped
random power spectral density noise specified below.
c. Linear Random Non-Operating Vibration
The drive will not incur physical damage or have non-recoverable errors after being subjected to the power spectral density noise
specified below.
2.8 Acoustics
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.
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

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:
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 HDD and SSD Regulatory Compliance and Safety
For the latest regulatory and compliance information see: https://www.seagate.com/support/ scroll to bottom of page and click
the Seagate HDD and SSD Regulatory Compliance and Safety link.
2.12.1 Regulatory Models
The following regulatory model number represent all features and configurations within the series:
Regulatory Model Numbers: STL010
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.

2.15 Product warranty
Beginning on the date of shipment to the customer and continuing for the period specified in the purchase contract, Seagate
warrants that each product (including components and subassemblies) that fails to function properly under normal use due to
defect in materials or workmanship or due to nonconformance to the applicable specifications will be repaired or replaced, at
Seagate’s option and at no charge to the customer, if returned by customer at customer’s expense to Seagate’s designated facility in
accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer. For
more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate products on the purchase
documentation.
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.
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.

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 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 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.
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).
3.4.1 Mechanical specifications
Refer to Figure 6 for detailed mounting configuration dimensions. See “Drive mounting” on page 23.
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.

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. F 27
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. F 28
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 9:
• 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.
Seagate Exos 7E8 SATA Product Manual, Rev. F 29
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 8 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.

The Identify Device command (command code ECH) transfers information about the drive to the host following power up. The data is
organized as a single 4096-byte block of data, whose contents are shown in Table 9 on page 31. All reserved bits or words should be
set to zero. Parameters listed with an “x” are drive-specific or vary with the state of the drive. See Section 2.0 on page 7 for default
parameter settings.
The following commands contain drive-specific features that may not be included in the Serial ATA specification

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
Table 11 Set Features command values
02HEnable write cache (default).
03HSet transfer mode (based on value in Sector Count register).
Sector Count register values:
00HSet PIO mode to default (PIO mode 2).
01HSet PIO mode to default and disable IORDY (PIO mode 2).

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.
Table 12 S.M.A.R.T. commands

Note If an appropriate code is not written to the Features Register, the
command is aborted and 0x 04 (abort) is written to the Error register.
