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.

• 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 pa rallel ATA easy by providing legacy softwar 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 ada pter cont ains a set of registe rs that sha dow the conte nt s of the trad it ional devic e regi s­ters, 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.

2.6 Seek time

Seek measurem ent s a re t ake n wi th nom inal po w er a t 25 °C amb ient temperature. All times are m easu red 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.

T yp ical seek times (msec) Read Write

Track-to-track <0.8 <1.0
Average <12.9 <13.9
Average latency: 4.16 4.16

Note. These drives ar e de si gned to consisten tl y me et t he se ek t imes r epr esente d in thi s manu al. P hysical

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

2.8 Power specifications

The drive recei ve s D C po we r ( +5V or +12V ) t hrou gh a native SA TA power connector. See Figure 4 on page 22.

2.8.1 Power consumption

Power requiremen ts fo r the drive s are listed i n the t able on pa ge 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.

• 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 represents the
worst-case power consumption, using only random seeks with read or write latency time. This mode is not
typical and is provided for worst-case information.

• Read/write power and current

Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-msec
delay, then a 16-sector read followed by a 32-msec delay.

• Operating power and current

Operating powe r is me asure d usi ng 40 p ercen t ran dom seeks, 4 0 per cent r ead/ wri te m ode ( 1 write for each
10 reads) and 20 percent drive idle mode.

• Idle mode power

Idle mode power is measu red with the drive up to speed, with servo elec tron ics 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.

Figure 2. Typical 12V startup and operation current profile

2.8.2 Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on
the +12 volt line or an equivalent 15-ohm resistive load on the +5 volt line.

• Using 12-volt power, the drive is expected to operate with a maxi m um of 120 mV peak-to -pea k square- wave
injected noise at up to 10 MHz.

• 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.

2.8.4 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:

Power modes Heads Spindle Buffer

Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled

• 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
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 disc access is necessary.

2.14 Environmental protection

Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemica l subst ances .

2.14.1 European Union Restriction of Hazardous Substances (RoHS)

The European U nion Restr icti on of Hazard ous S ubst ance s (RoHS ) Dire cti ve re strict s the p resen ce of ch emic al
substances, incl uding Lead (Pb), in electronic products effective July 2006.

A number of parts and materials in Seagate products are procured from external suppliers. We rely on the
rep-resentat ions o f our sup pl iers reg ardi ng the pr esence of RoHS subst ances in these part s and mate rials. Our
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document
their compliance wi th our re quire ment s by pro v iding mat eri al conte nt declar ati ons for all par ts an d mater i als for
the disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion
of any RoHS-regulated substance in such parts or materials.

2.15 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 , nicke l and gold films used i n Seag ate pr oduct s are especi ally sen s itive to the p resen ce of sulf ide, chlo­ride, 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 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.

3.0 Configuring and mounting the drive

This section contains the specifications and instructions for configuring and mounting the drive.

3.1 Handling and static-discharg e 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:

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 plugg ed into a grounded outlet. Wear a grounded wrist strap through out 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.

22

DiamondMax 20 Serial ATA Product Manual, Rev. A

3.2 Configuring the drive

S

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 SATA­equipped mother boar d or hos t ada pter may use a chipset that do es no t supp ort SATA speed autonegotiation . If
you have a motherboard or host adapter that does not support autonegotiation:

• Configure the jumper bl ock wit h a jump er as shown in F igure 3 b elow to limit the da ta transfe r rate to 1.5 Gbi ts
per second (and leave the drive connected to the SATA-equipped motherboard or host adapter that doesn’t
support autonegotiation) or

• Install a SATA host adapter that supports autonegotiation, set the drive jumper block to “3 Gbits per second
operation” (see Fi gure 3 below), and connect the drive to that adapter. T his option has the benefit of not l imiting
the drive to a 1.5 Gbits/sec transfer rate.

3.3 Serial ATA cabl es and connect ors

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 inches). See Table 6
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 4.

3.4 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 hol es. See Fi gur e 5 for drive moun ting di mensio ns. Follow these impor t ant moun ting preca u­tions when mounting the drive:

• Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling.

• Use only 6-32 UNC mounting screws.

• The screws should be inserted no more than 0.150 inch (3.81 mm) into the bottom or side mounting holes.

• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

power up. The data is organized as a single 512-byte block of data, whose contents are shown in Table 7 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 implementation of var ious features that the drive sup port s. When th e dr i ve r eceives
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-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://seatools.seagate.com.

This drive is ship ped w ith S. M.A.R .T. fe ature s disab led. You mu st ha ve a r ecent 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.
