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

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 you to

install a Serial ATA host adapter and Serial ATA disk drive in your current system and expect all of your 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 International Organization: Serial ATA (Revision 2.6). The specification can be downloaded from www.serialata.org.

Standard models

ST500VT000 - 1DK142

ST500VT001 - 1K6142

ST320VT000 - 1DK14C

ST250VT000 - 1DK141

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.

Drive Specifications

2.6 Start/stop times

2.7 Power Specifications

The drive receives DC power (+5V) through a native SATA power connector (refer to Figure 2).

2.7.1 Power consumption

Power requirements for the drives are listed in the table in Table 4. Typical power measurements are based on an average of drives tested, under

nominal conditions, at 25°C ambient temperature. These power measurements are done with Interface Power Management modes like HIPM

and DIPM enabled.

Spinup power

Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

Seek mode

During seek mode, the read/write actuator arm moves toward a specific position on the disk surface and does not execute a read or write

operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100 ms. This mode is not

typical.

Read/write power and current

Read/write power is measured with the heads on track, based on three 63 sector read or write operations every 100 ms.

Idle mode power

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.

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.

2.7.3 Voltage tolerance

Voltage tolerance (including noise):

 +5V ± 5%

2.7.4 Power management modes

The drive provides programmable power management to provide greater energy efficiency. In most systems, power management is controlled

through the system setup program. The drive features the following power-management modes:

Active mode

The drive is in active mode during the read/write and seek operations.

Idle mode

The buffer remains enabled, and the drive accepts all commands and returns to active mode any time disk 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 disk access is necessary.

Sleep mode

The drive enters sleep mode after receiving a sleep command from the host. In sleep mode, the drive buffer 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 disk access is necessary.

Note Equivalent resistance is calculated by dividing the nominal voltage by

the typical RMS read/write current.

The maximum nonoperating vibration levels that the drive may experience without incurring physical damage or degradation in performance

when subsequently put into operation are specified below.

2.9 Acoustics

Drive emission of sound is measured consistent with the ECMA-74 and its referenced standards. Testing is conducted at room temperature

(approximately 25°C). Emission levels are reported as the total A-weighted sound power levers for steady state, idle, and active seeks modes of

operation.

2.9.1 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 the lower limit for the threshold curve* 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.

*Defined as the median curve given by ISO 389-7 (Tf curve) minus 10dB at all frequencies.

Configuring and Mounting the Drive

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 in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave

relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one Serial ATA host adapter,

the host operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if they are Device 0

(master) devices.

3.2.1 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). Refer to 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, you can connect the drive

as shown in Figure 2.

Figure 2 Attaching SATA Cabling

Each cable is keyed to ensure correct orientation. Seagate Video 2.5 HDD drives support latching SATA connectors.

CAUTION

• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the

drive’s exposure to ESD.

• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the

metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap

throughout the entire installation procedure.

• 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.

4.3.2 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 12 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).

4.3.3 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. 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.

Table 13 S.M.A.R.T. Commands

Code in features register S.M.A.R.T. command

D0HS.M.A.R.T. Read Data

D2HS.M.A.R.T. Enable/Disable Attribute Autosave

D3HS.M.A.R.T. Save Attribute Values

D4HS.M.A.R.T. Execute Off-line Immediate (runs DST)

D5HS.M.A.R.T. Read Log Sector

D6HS.M.A.R.T. Write Log Sector

D8HS.M.A.R.T. Enable Operations

D9HS.M.A.R.T. Disable Operations

DAHS.M.A.R.T. Return Status

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.
