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

in the table below are defined as follows:
• Average seek time is determined by averaging the time to complete 1,000 seeks of random length.
• Average latency is the time required for the drive to rotate 1/2 of a revolution and on average is
incurred after a seek completion prior to reading or writing user data.
• Startup time is the time elapsed between the supply voltages reaching operating range and the
drive being ready to accept all commands.
• Actual rotational speed can be different a little.
• Performance specification is limited to the room temperature & normal voltage condition.

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.

Unpacking, Configuring and Mounting the Drive
This chapter describes how to unpack, mount, configure and connect a BarraCuda. It also describes how to install the drive in systems.
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
3.2
• Keep the drive in the electrostatic discharge (ESD) bag until 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 mounting 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.
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 9 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, users can connect the
drive as shown in1.

3.3
Drive Mounting
Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes. Refer to2
and Figure 2 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:
•
Allow a minimum clearance of 0.030 in (0.76 mm) around the entire perimeter of the drive for cooling.
•
Use only M3 x 0.5 mounting screws.
•
Do not overtighten the mounting screws. Maximum torque: 4.0 in-lb (0.4519 N-m).
•
Four (4) threads (0.080 in, 2.032 mm) minimum screw engagement recommended.
•
Avoid excessive drive distortion when mounting. Refer to the following specifications for stiffness/deflection information:
Top cover stiffness/deflection
Operating: no performance degradation, emitted noise,
mechanical damage, or hard errors
10 mm probe: 2.0kgf (typical)

Notes
1 All pins are in a single row, with a 1.27 mm (0.050 in) pitch.
2 The comments on the mating sequence apply to the case of backplane blindmate connector only. In this case, the mating sequences are:
• the ground pins P4 and P12.
• the pre-charge power pins and the other ground pins.
• the signal pins and the rest of the power pins.
3 There are three power pins for each voltage. One pin from each voltage is used for pre-charge when installed in a blind-mate backplane
configuration.
4 All used voltage pins (Vx) must be terminated.

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:

Enable write cache (default).
03H

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. Users 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.
