only 75 nanometers.  
• Seagate OptiCache™ technology boosts overall performance by as much as 45% over the previous  
generation.  
• Seagate SmartAlign™ technology provides a simple, transparent migration to Advanced Format 4K sectors  
• Quiet operation.  
• Compliant with RoHS requirements in China and Europe.  
• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.  
• Support for S.M.A.R.T. drive monitoring and reporting.  
• Supports latching SATA cables and connectors.  
• Worldwide Name (WWN) capability uniquely identifies the drive.  
1.1 About the SATA interface  
The Serial ATA (SATA) 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, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was  
designed to allow you to install a SATA host adapter and SATA disk drive in your current system and expect all of  
your existing applications to work as normal.  
The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is  
no master/slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one  
SATA 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.  
The SATA 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.  
Barracuda SATA Product Manual, Rev. G

Introduction  
The SATA host adapter contains a set of registers that shadow the contents of the traditional device registers,  
referred to as the Shadow Register Block. All SATA devices behave like Device 0 devices. For additional  
information about how SATA emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA  
The host adapter may, optionally, emulate a master/slave environment to host software where two devices on  
separate SATA 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 SATA environment.

Average rate of <55TB/year. The MTBF specification for the drive assumes the I/O workload does not  
exceed the average annualized workload rate limit of 55TB/year. Workloads exceeding the annualized  
rate may degrade the drive MTBF and impact product reliability. The average annualized workload rate  
limit is in units of TB per year, or TB per 8760 power-on hours. Workload rate limit = TB transferred ×  
(8760/recorded power-on hours).

2.6 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 5000 measurements of seeks between  
random tracks, less overhead.

These drives are designed to consistently meet the seek times represented in this manual. Physical 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.

2.8.1 Power consumption  
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.  
• 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-ms delay,  
then a 16-sector read followed by a 32-ms delay.  
• Operating power and current  
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10  
reads) and 20 percent drive idle mode.  
• 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 mode.

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 10MHz.  
• 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 10MHz.  
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

• 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 disk  
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 disk 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

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  
than the threshold defined by the China RoHS MCV Standard.  
"X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over the  
threshold defined by the China RoHS MCV Standard.  
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.  
3.2 Configuring the drive  
Each drive on the SATA interface connects point-to-point with the SATA 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 SATA 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.  
SATA 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 SATA-equipped  
motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation.  
3.3 SATA cables and connectors  
The SATA 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 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, you can connect the drive as illustrated in Figure 1.

Each cable is keyed to ensure correct orientation. Barracuda drives support latching SATA connectors.  
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. Refer to Figure 2, Figure 3, and Figure 4 for drive mounting dimensions. Follow these  
important mounting precautions when mounting the drive:  
• Allow a minimum clearance of 0.030 inches (0.76mm) 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 (3.81mm) into the bottom or side mounting holes.  
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

4.0 SATA Interface  
These drives use the industry-standard Serial ATA (SATA) interface that supports FIS data transfers. It supports  
ATA programmed input/output (PIO) modes 0 to 4; multiword DMA modes 0 to 2, and Ultra DMA modes 0 to 6.  
For detailed information about the SATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment”  
specification.  
4.1 Hot-Plug compatibility  
Barracuda drives incorporate connectors which enable you to hot plug these drives in accordance with the SATA  
4.2 SATA device plug connector pin definitions  
Table 9 summarizes the signals on the SATA interface and power connectors.

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.  
• All used voltage pins (Vx) must be terminated.  
4.3 Supported ATA commands

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

4.3.3 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 D4 ) that eliminates  
H
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:  
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.
