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).  
For more information on FIPS 140-2 Level 2 certification see See Section 5.0 on page 29.  
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.

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

Seek time  
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using  
drive diagnostics. The specifications in the table below are defined as follows:  
• Track-to-track seek time is an average of all possible single-track seeks in both directions.  
• Average seek time is a true statistical random average of at least 5,000 measurements of seeks between  
random tracks, less overhead.

Note. These drives are designed to consistently meet the seek times represented in this manual. Physical  
seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted  
values. However, due to the manner in which these drives are formatted, benchmark tests that  
include command overhead or measure logical seeks may produce results that vary from these  
specifications.

Power specifications  
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.

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.

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

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.

These drives comply with the performance levels specified in this document when subjected to a maximum  
operating shock of Read 70 Gs and Write 40 Gs based on half-sine shock pulses of 2ms. Shocks should not be  
repeated more than once every 2 seconds.  
3.9.4.2  
Nonoperating shock  
The nonoperating shock level that the drive can experience without incurring physical damage or degradation  
in performance when subsequently put into operation is 400 Gs based on a nonrepetitive half-sine shock pulse  
of 2ms duration.

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)

Reliability  
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)  
3.12.1  
The product shall achieve an Annualized Failure Rate - AFR - of 0.62% (Mean Time Between Failures - MTBF  
- of 1.4 Million hrs) when operated in an environment that ensures the HDA case temperatures do not exceed  
40°C. Operation at case temperatures outside the specifications in Section 3.9 may increase the product Annu-  
alized Failure Rate (decrease MTBF). AFR and MTBF are population statistics that are not relevant to individ-  
ual units.  
AFR and MTBF specifications are based on the following assumptions for business critical storage system  
environments:  
• 8760 power-on-hours per year.  
• 250 average motor start/stop cycles per year.  
• Operations at nominal voltages.  
• Systems will provide adequate cooling to ensure the case temperatures do not exceed 40°C. Temperatures  
outside the specifications in Section 3.8 will increase the product AFR and decrease MTBF.

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  
guideline. Please refer to Section 4.5 for final cooling requirements.  
• 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.

Cooling  
Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding  
the drive will not exceed temperature conditions specified in Section 3.9.1, "Temperature."  
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-  
lines of Section 3.9.1 are met.

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  
(TCG) Enterprise Storage Specifications as detailed in Section 3.14.2.  
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  
key is used for each of the drive's possible16 data bands (see Section 6.5).  
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  
(non-SED) models as listed in Table 6:  
• 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.
