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 normally 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 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

AT Attachment” specification. The specification can be downloaded from http://www.serialata.org.

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.

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) through a native SATA power connector.

2.9.1 Power consumption

Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on

an average of drives tested, under nominal conditions, 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.

• Seek mode

During seek mode, the read/write actuator arm moves toward a specific position on the disc 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 msecs. 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 msecs.

• 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 model

Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on

the +5 volt line.

Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave

injected noise at up to 10 MHz.

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

current.

Power-management modes

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

you can control power management 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 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 in Self Refresh Low Power mode, 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 buffer

is in Self Refresh Low Power mode, the heads are parked and the spindle is at rest. The drive leaves Sleep

mode after it receives a Hard Reset or Soft Reset from the host. After receiving a reset, the drive exits Sleep

mode and enters Standby mode 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.

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 corro-

sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-

ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,

chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components

Momentus 7200.3 SATA Product Manual, Rev. C

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.

3.1

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:

• 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 only by its edges or frame.

• The drive is 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.

Momentus 7200.3 SATA Product Manual, Rev. C

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. This means both drives behave as if they are

Device 0 (master) devices.

Serial ATA drives are designed for easy installation with no jumpers, terminators, or other settings. It is not nec-

essary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector

is for factory use only.

Identify Device command

The Identify Device command (command code EC ) transfers information about the drive to the host following

power up. The data is organized as a single 512-byte block of data, whose contents are shown in the table on

page 27. 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 3 for default parameter settings.

The following commands contain drive-specific features that may not be included in the Serial ATA specifica-

tion.

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:

Table 8:

Set Features command values

Enable write cache (default).

Set transfer mode (based on value in Sector Count register).

Sector Count register values:

00 Set PIO mode to default (PIO mode 2).

01 Set PIO mode to default and disable IORDY (PIO mode 2).

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-8 Standard.

SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 ) that elimi-

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

http://seatools.seagate.com.

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.
