Seagate LD25 Series 5400.2 drives are 2.5-inch form factor products designed for non-notebook PC applica-  
tions such as:  
• Consumer electronics (gaming, small personal video recorders (PVRs) and digital video recorders (DVRs)  
• Ultra-small desktop PCs  
• Internet appliances  
• Printers, copiers, and other devices that may use disc drives for data storage  
LD25 Series 5400.2 drives are quieter, lighter and use less power than 3.5-inch drives. They are ideal for appli-  
cations requiring the form and fit of a notebook drive but without some of the design specifications required by  
notebook drives such as high shock tolerance, high performance, and power management. LD25 Series drives  
are not presently suited for notebook applications or other environments with high operating temperatures.  
These drives provide the following key features:  
• 5,400-RPM spindle speed  
• 2-Mbyte buffer  
• High instantaneous (burst) data transfer rates  
• Perpendicular recording and Tunneling Magnetoresistive (TMR) recording heads  
• State-of-the-art cache and on-the-fly error-correction algorithms  
• Full-track multiple-sector transfer capability without local processor intervention  
• Quiet operation  
• 500 Gs nonoperating shock  
• The 3D Defense System™ (Drive Defense, Data Defense, and Diagnostic Defense) provides the industry’s  
most comprehensive protection for disc drives  
• Support for S.M.A.R.T. drive monitoring and reporting  
• Support for Read Multiple and Write Multiple commands

Seek time  
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using  
drive diagnostics. The specifications 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.

Note. 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 or exceed 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.

Power specifications  
The drive receives DC power (+5V) through the 4-pin power connector.  
2.8.1 Power consumption  
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on  
an average of drives tested, under nominal conditions, at 25°C ambient temperature.  
• Spinup power  
Spinup power is measured fromthe time ofpower-onto thetimethat 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 is measured based on  
three random seek operations every 100 msecs. This mode is not typical.  
Read/write power and current  
Read/write power is measured with the heads on track, based on three 63 sector read or write operations  
every 100 msecs.  
• 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 model

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

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 in performance mode, 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.

Acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound power levels. All measurements are con-  
sistent 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.  
Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is  
defined by the following equation:  
(Number of seeks per second = 0.4 / (average latency + average access time)

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 mar-  
keted to the customer. As a subassembly, no Federal Communications Commission verification or certification  
of the device is required.  
Seagate Technology LLC has tested this device in enclosures as described above to ensure that the total  
assembly (enclosure, disc 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 installa-  
tion. 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 sug-  
gestions. 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 Super-  
intendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Refer to publication num-  
ber 004-000-00345-4.

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)  
The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical  
substances, including 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-  
resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our  
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document  
their compliance with our requirements by providing material content declarations for all parts and materials 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.  
Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws  
and regulations which restrict chemical content in electronic products. These systems include standard operat-  
ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, laboras-  
tory analytical validation testing, and an internal auditing process to ensure that all standard operating  
procedures are complied with.  
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 corro-  
sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-  
ver, 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 vulca-  
nized 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.

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 dis-  
charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:  
Caution:  
• Keep the drive in the electrostatic discharge (ESD) bag until you are 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 only by its edges or frame.  
• The drive is 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  
Mounting the drive  
Mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See  
Figure 2 for drive mounting dimensions. Follow these important mounting precautions 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 M3 UNC mounting screws.  
• Do not overtighten the mounting screws (maximum torque: 4.0 inch-lb).  
• Four (4) threads (0.080 inches) minimum screw engagement recommended.

How to configure and connect Serial ATA (SATA) drives  
How to configure the drive  
3.4.1.1  
Each drive on the SATA interface connects in a point-to-point configuration with the SATA 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 SATA host adapter, the host operating system views the two devices as if they  
were both “masters” on two separate ports. This means both drives behave as if they are Device 0 (master)  
devices.  
SATA drives are designed for easy installation with no jumpers, terminators, or other settings. It is not neces-  
sary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector is  
for factory use only.

(factory use only)  
Figure 4. SATA connectors  
3.4.1.2  
How to connect SATA cables  
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 7 for con-  
nector 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 5.

3.4.2 How to configure Parallel ATA (PATA) drives  
Use the options jumper block shown in Figure 6 to configure the drive for operation. This jumper block is the  
4-pin header adjacent to pins 1 and 2 of the I/O signal pins. For additional information about using the Cable  
select option, see Section 3.4.2.1.1.  
3.4.2.1  
How to configure the drive as a master or slave  
Refer to Figure 6 to set the master, slave, or cable select option. The “Master or single drive” option is the fac-  
tory default setting.  
Drive is master (or single drive)  
Drive is slave  
Cable select  
Figure 6. Jumper settings  
3.4.2.1.1  
How to use the cable-select option  
Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28,  
CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To  
enable cable select, set a jumper as shown in Figure 6. Refer to your computer manual to determine whether  
your computer supports this option.

Identify Device command  
The Identify Device command (command code EC ) transfers information about the drive to the host following  
H
power up. The data is organized as a single 512-byte block of data, whose contents are shown in the table 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 specifica-  
tion.

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 inter-  
rupt. 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:

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 moni-  
tors 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:  
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.
