1.0 Introduction  
This manual describes the functional, mechanical and interface specifications for the following Seagate®  
Barracuda® Green SATA model drives:  
ST2000DL003  
ST1500DL003  
These drives provide the following key features:  
• 5900 RPM spindle speed  
• Seagate® SmartAlign™ technology manages read-modify-write conditions dynamically in the drive without  
host computer intervention, allowing a 4K drive to behave like a legacy 512-byte sector drive without the  
necessity of a hardware utility.  
• High instantaneous (burst) data-transfer rates (up to 600MB per second)  
• Perpendicular recording, Tunneling Magnetoresistive (TMR) recording heads and EPRML technology, for  
increased areal density  
• State-of-the-art cache and on-the-fly error-correction algorithms  
• Native Command Queueing with command ordering to increase performance in demanding applications  
• Full-track multiple-sector transfer capability without local processor intervention  
• 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 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 disk drive in your current system  
and expect all of your existing applications to work as normal.  
Barracuda Green SATA Product Manual, Rev. D

Introduction  
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.  
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.  
Note  
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 3.0”. The specification can be

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 5,000 measurements of seeks between ran-  
dom 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.

Time-to-ready may be longer than normal if the drive power is removed without going through normal OS power-  
down procedures.  
2.8 Power specifications  
The drive receives DC power (+5V or +12V) through a native SATA power connector. (Refer to Figure 3 ).  
2.8.1 Power consumption  
Power requirements for the drives are listed in Table 2 on page 15. 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.  
• 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  
+12V line or an equivalent 15-ohm resistive load on the +5V line.  
• Using 12-V 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-V power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave  
injected noise at up to 10MHz.  
Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.  
2.8.3 Voltage tolerance  
Voltage tolerance (including noise):  
5V 5%  
12V 10%  
2.8.4 Power-management modes  
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:

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 spec-  
ifiable 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 com-  
mands 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  
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 disk access is necessary.

Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All  
measurements are consistent with ISO document 7779. Sound power measurements are taken under essentially  
free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.  
For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the  
following equation:

2.10.1 Test for Prominent Discrete Tones (PDTs)  
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this  
process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-  
7) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of  
tone ratios according to Annex D of the ECMA-74 standards.  
2.11 Electromagnetic immunity  
When properly installed in a representative host system, the drive operates without errors or degradation in  
performance when subjected to the radio frequency (RF) environments defined in the following table:

Drive Specifications  
2.14.3 FCC verification  
These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as  
an external device). As such, each drive is considered to be a subassembly even when it is individually marketed  
to the customer. As a subassembly, no Federal Communications Commission verification or certification of the  
device is required.  
Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure,  
disk drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant  
to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interference to  
radio and television reception.  
Radio and television interference. This equipment generates and uses radio frequency energy and if not  
installed and used in strict accordance with the manufacturer’s instructions, may cause interference to radio and  
television reception.  
This equipment is designed to provide reasonable protection against such interference in a residential installation.  
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does  
cause interference to radio or television, which can be determined by turning the equipment on and off, you are  
encouraged to try one or more of the following corrective measures:  
• Reorient the receiving antenna.  
• Move the device to one side or the other of the radio or TV.  
• Move the device farther away from the radio or TV.  
• Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.  
If necessary, you should consult your dealer or an experienced radio/television technician for additional  
suggestions. You may find helpful the following booklet prepared by the Federal Communications Commission:  
How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the  
Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication  
number 004-000-00345-4.

2.15 Environmental protection  
Seagate designs its products to meet environmental protection requirements worldwide, including regulations  
restricting certain chemical substances.  
2.15.1 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.  
2.15.2 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.  
2.16 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  
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 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 SATA-equipped  
motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation.  
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 in). 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 3.

Each cable is keyed to ensure correct orientation. Barracuda Green 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. See Figure 4 for drive mounting dimensions. Follow these important mounting  
precautions when mounting the drive:  
• Allow a minimum clearance of 0.030 in (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 in (3.81mm) into the bottom or side mounting holes.  
Do not overtighten the mounting screws (maximum torque: 6 in per lb).

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.

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 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.

If an appropriate code is not written to the Features Register, the command is aborted and 0x04 (abort) is  
written to the Error register.
