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 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 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: High Speed Serialized
AT Attachment” specification. The specification can be downloaded from www.serialata.org.

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.

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 maximum of 120 mV peak-to-peak 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-management modes

PowerChoiceTM power management

Drives using the load/unload architecture provide programmable power management to tailor systems for per­formance and greater energy efficiency.

The table below lists the supported PowerChoice modes. The further you go down in the table, the more power
savings you get. For example, Idle_B mode results in greater power savings than Idle_A mode. Standby mode
results in the greatest power savings.

Mode Description

Idle_A Reduced electronics

Idle_B Heads unloaded. Disks spinning at full RPM

Idle_C Heads unloaded. Disks spinning at reduced RPM

Standby Heads unloaded. Motor stopped (disks not spinning)

PowerChoice can be invoked using one of these two methods:

• Extended Power Conditions (EPC) Set Features Command method-Enable and initialize the idle condition
timers.

• Standby Immediate and Idle Immediate command method-Use the EPC Set Features Command. This allows
the host to directly transition the drive to any supported PowerChoice mode. The drive preserves the existing
idle power settings.

PowerChoice reporting methods

PowerChoiceTM provides these reporting methods for tracking purposes:

Check Power Mode Reports

• Current power condition

Power Condition Log Reports

• Idle condition enabled/disabled

• If timer is changeable

• Typical recovery time from extended power conditions

• Current timer setting and Manufacturer default timer settings

2.14 Environmental protection

Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemical substances.

2.14.1 European Union Restriction of Hazardous Substances (RoHS) Directive

The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemi­cal substances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic prod­ucts, effective July 2006. This drive is manufactured with components and materials that comply with the RoHS
Directive.

2.14.2 China Restriction of Hazardous Substances (RoHS) Directive

This product has an Environmental Protection Use Period (EPUP) of 20 years. The following
table contains information mandated by China's "Marking Requirements for Control of Pollution
Caused by Electronic Information Products" Standard.

"O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower

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, 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
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 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-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:

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 Serial ATA Product Manual, Rev. B 19

3.2 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 SATA­equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation. If
you have a motherboard or host adapter that does not support autonegotiation:

• Install a jumper as shown in Figure 3 below to limit the data transfer rate to 1.5 Gbits per second (and leave
the drive connected to the SATA-equipped motherboard or h
or

• Install a SATA host adapter that supp

orts autonegotiation, leave the drive jumper block set to “Normal
operation” (see Figure 3 below), and connect the drive to that adapter.

3.3 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 inches). 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 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 holes. See Figure 5 for drive mounting dimensions. Follow these important mounting precau­tions when mounting the drive:

• Allow a minimum clearance of 0.0
a guideline. Please refer to Section 3.5 for final cooling requirements.

• Use only M3 x 0.5 metr

• Four (4) threads (0.080 inches) minimum screw engagement recommended. Also ensure maximum screw
le

ngth does not bottom out in mounting holes.

• Do not overtighten the mounting screws (maximum torque: 4.5 inch-lb, ± 0.45 in-lb).

Constellation Serial ATA Product Manual, Rev. B 21

3.5 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 2.9.1, "Ambient 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 temper­ature measurement guidelines described in Section 2.9.1.

Forced air flow may be required to keep temperatures at or below the temperatures specified in Section 2.9.1
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 6. The air-flow pat­terns 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 guide­lines of Section 2.9.1 are met.

Note. Air flows in the direction shown (back to front)

or in reverse direction (front to back)

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 Table 6 on
page 25. 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 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:

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 D4

) that elimi-

H

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

http://seatools.sea

gate.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.
