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 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 transiti o n from pa rallel ATA easy by providi ng legacy sof twar e suppo rt. S erial
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 cont ai ns a set of registe rs that sha dow the conte nt s of the trad iti onal device r egis­ters, 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 http://www.serialata.org.

2.9 Power specifications

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

2.9.1 Power consumption

Power requiremen ts for the dr iv es are listed i n the ta ble on p age 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 re aches operating speed.

• Seek mode

During seek mod e, the read /write actuator arm move s toward a spe cific positi on on the d isc surface and does
not execute a read or write operati on. Servo ele ctronics ar e acti ve. Seek mode power is mea sure d 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

2.9.4 Power-manag ement mo des

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:

Table 4: Power management modes

Power modes Heads Spindle Buffer

Active (operating) Tracking Rotating Full power
Idle, performance Tracking Rotating Self refresh—low power
Idle, active Floating Rotating Self refresh—low power
Idle, low power Parked Rotating Self refresh—low power
Standby Parked Stopped Self refresh—low power
Sleep Parked Stopped Self refresh—low power

• 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 Immediat e c omma nd. If the ho st 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 tim er delay is establi shed using a Standb y or Idle command. In Sta ndby
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 enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sl eep mod e, th e dr ive 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.

2.16 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 electr onic dr i ve com ponen t reliab ilit y can be af fecte d by th e i nst allation environment. Th e si l-
ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,
chloride, and nitr ate c ont ami na nt s. S ulfur is found to be the m ost dam aging . In ad di tion, e lectron i c comp onent s
should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or
exposed to an am bient rel at ive hum idity gr eate r th an 9 5%. Mat erial s used in cabin et fa bri cation , 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.

3.2 Configuring the drive

S

r

r

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 sep a rate ports. This means both drives b ehave as if they are
Device 0 (master) devices.

Serial ATA drives ar e des ig ned f or e asy inst all ation wi th no jump ers, t erm inator s, or other setti n gs. It is not n ec­essary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector
is for factory use only.

4.3.1 Identify Device command

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 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 specifica­tion.

4.3.2 Set Features command

This command con trols the implement ation of var ious features that the dr iv e sup port s. 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:

4.3.3 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 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-8 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://seatools.seagate.com.

This drive is ship ped w ith S. M.A.R .T. features disabled. You must have a recent BI OS or so ft wa re pa ckage 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.
