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 quiet er, lighter and use less pow er th an 3. 5-inch dri ves. The y 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 pe rfor mance , and pow er man agem ent. L D25 S eries d rives
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

2.14 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemica l subst ances .
2.14.1 European Union Restriction of Hazardous Substances (RoHS)
The European U nion Restr icti on of Hazard ous S ubst ance s (RoHS ) Dire cti ve re strict s the p resen ce of ch emic al
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 representations 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 wi th our re quire ment s by providing material conte nt declar ations for al l par ts an d mater ial s 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 system s in place to en sure ongoing complian ce with the RoHS Directive and all laws
and regulations which restrict chemical conte nt in electron ic produ cts. T hese system s include sta ndar d operating procedures that ensure tha t restr icted subst an ces are not utilized in ou r manufactur ing ope ratio ns, laborastory 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 corrosive chemicals as electr onic dr i ve com ponen t reliab ilit y can be af fecte d by th e i nst allation environment. The sil-
ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,
chloride, and nitr ate c ont ami na nt s. S ulfur is found to be the m ost dam aging . In ad di tion, e lectron i c comp onent s
should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or
exposed to an am bient rel at ive hum idity gr eate r th an 9 5%. Mat erial s used in cabin et fa bri cation , 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.

3.4.1 How to configure and connect Serial ATA (SATA) drives
3.4.1.1 How to configure the drive
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 necessary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector is
for factory use only.

Notes:
1. All pins are in a single row, with a 1.27 mm (0.050”) 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 pints 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.

4.2 Parallel ATA (PATA) Interface
These drives use the industry-standard ATA task file interface that supports 16-bit data transfers. It supports
ATA programmed input/output (PIO) modes 0–4; multiword DMA modes 0–2, and Ultra DMA modes 0–5. The
drive also supports the use of the IORDY signal to provide reliable high-speed data transfers.
For detailed information about the ATA interface, refer to the draft of AT Attachment with Packet Interface
Extension (ATA/ATAPI-6), NCITS T13 1410D, subsequently referred to as the Draft ATA-6 Standard.

4.5 Set Features command
This command con trols the implement ation of var ious features that the dr iv e sup port s. 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.

4.6 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 D4H) that eliminates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:
http://seatools.seagate.com.
This drive is ship ped wi th S. M.A.R. T. features disab led. You must have a recent BI OS or software pa ckage 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.
