2.7 Seek time
Seek measurements are taken with nominal power. 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.

2.9 Power specifications
The drive receives DC power (+5V) through the interface connector.
2.9.1 Power consumption
Power requirements for the drives are listed in the table on page 11. Typical power measurements are based
on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient temperature.
• Spinu p power
Spinup power is measured from the time of power-on to the time that the drive spindle re aches operating speed.
• Seek mode
During seek mod e, the read /write actuator arm move s toward a spe cific positi on on the d isc surface and does
not execute a read or write operati on. Servo ele ctronics ar e acti ve. Seek mode power is mea sure d 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

2.9.4 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:
Power modes Heads Spindle Buffer
Active (operating) Tracking Rotating Enabled
Idle, performance Tracking Rotating Enabled
Idle, active Floating Rotating Disabled
Idle, low power Parked Rotating Disabled
Standby Parked Stopped Disabled
Sleep Parked Stopped Disabled
• Active mode
The drive is in Active mode during the read/write and seek operations.
• Idle mo de
The buffer remains enabled, 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 Immediat e c omma nd. If the ho st 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 tim er delay is establi shed using a Standb y or Idle command. In Sta ndby
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 enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sl eep mod e, th e dr ive 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 So ft Reset from the host. After recei ving a reset, the drive exits S leep mode and en ters 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 dela y times to zero. If the standby tim er reaches zero bef ore 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 disc access is necessary.

2.16 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemica l subst ances .
2.16.1 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
rep-resentat ions o f our sup pl iers reg ardi ng the pr esence of RoHS subst ances in these p arts and mate rials. 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 content in electronic products. These systems include standard
operat-ing procedures that ensure that restricted substances are not utilized in our manufacturing operations,
labora-tory analytical validation testing, and an internal auditing process to ensure that all standard operating
procedures are complied with.
2.17 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 allati on enviro nmen t. Th e silver, 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

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:
• 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 plugg ed into a grounded outlet. Wear a grounded wrist strap through out 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 Jumper settings
3.2.1 Master/slave configuration
Use the options jumper block shown in Figure 3 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
