2.5 Seek time
Seek measurem ent s a re t ake n wi th nom inal po w er a t 25 °C amb ient 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
random tracks, less overhead.
Table 2: Typical seek times
T yp ical seek times (msec) Read Write
Track-to-track 0.8 1.0
Average 18 20
Average latency: 4.16 4.16
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 a r e formatted, benchmark tests that include command
overhead or measure logical seeks may produce results that vary from these specifications.

2.7 Power specifications
The drive receives DC power (+5V and +12V) through a four-pin standard drive power connector.
2.7.1 Power consumption
Power requiremen ts for the dr iv es are lis ted in the ta ble on page 7. Typical power measu rem ent s are ba sed 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 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 operation. Servo electronics are active. Seek mode power represents the worstcase power consumption, using only random seeks with read or write latency time. This mode is not typical
and is provided for worst-case information.
• Operating power and current
Operating power is measured using a standard Consumer Storage Profile.
• Idle mode powe r
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.

2.7.2 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 -pea k square- wave
injected noise at up to 10 MHz.
• 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.

2.7.4 Power-manageme nt mo des
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 mode Heads Spindle Buffer
Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled
• 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 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 ti mer delay is establi shed using a Standb y 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 enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sleep mode, th e dr ive buf fer
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 delay times to zero. If the standby tim er reaches zero before an y 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.
2.8 Environmental specifications
2.8.1 Ambient temperature
Ambient temperature is defined as the temperature of the environment immediately surrounding the drive.
Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions for
standard models. Recommended measurement locations are shown in See Figure 6 on page 19.
Above 1,000 feet (305 meters), the maximum temperature is derated linearly to 44°C (112°F) at 10,000 feet
(3,048 meters).
Operating: 0° to 60°C (32° to 140°F)

2.13 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemica l subst ances .
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 part s 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 pro v iding mat eri al conte nt declar ati ons for all par ts an d mater i als 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.
2.14 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 , nicke l and gold films used i n Seag ate pr oduct s are especi ally sen s itive to the p resen ce of sulf ide, 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 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.

3.0 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:
• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation.
• 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- inst al led labels fr om the driv e or cover the m wi th additio nal labels. R emoval 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 Breather filt er hole prec autions
This section contains information regarding the precautions which should be taken regarding the breather filter
hole in Seagate hard disc drives. Proper precautions should be taken to ensure full functionality and prevent
possible damage to the drive.
Breather hole
Do not cover or seal
this hole.
Figure 3 Breather filter hole location
Caution: Do not cover, seal, or insert any object into this hole.
This hole has two purposes:
• To allow condensation inside the hard disc to escape
• To allow air pressure inside the hard disc to equalize with ambient pressure
Note. If this hole is covered, sealed, or penetrated by any object, drive reliability may be compromised
and could lead to permanent damage—doing so voids the warranty.

3.3.2 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 on pins 5 and 6 as shown in Figure 4. Refer to your computer manual to
determine whether your computer supports this option.
3.3.3 Alternate capacity jumper
Some older computers may “hang” at startup if their BIOS detects a disc drive with a capacity greater than 32
Gbytes. This limits the drive’s capacity to 32 Gbytes when the alternate capacity jumper is used. To access the
full capacity of the drive, you can:
• Update the BIOS
• Use third-party software such as DiscWizard™ or Disk Manager
• Use a third-party host adapter
For drives with capacities greater than 32 Gbytes, the alternate capacity jumper changes the total available
LBA sectors to 32 Gbytes to solve issues with some BIOS during power on. The ATA Set Features subcommand “F1H Report Full Capacity Available” causes Identify Data words 60 and 61 to report the full capacity.
See Section 4.1.3 on page 27 for more details on the Set Features command.

Note. The drive supports bo th host and drive cabl e det ection. T he host det ect s the 80-conductor cable by
sampling pin 34, CBLID–, on the interface bus. The drive detects the 80-conductor cable by sensing a capacitor at the host side through the CBLID– signal. The result is reported in a Fast Rise
Detected bit (bit 13 of word 93 in the Identify drive parameter block).
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 hol es. See Fi gur e 6 for drive moun ting di mensio ns. Follow these impor t ant moun ting preca utions 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 6-32 UNC mounting screws.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb.).
• Do not use a drive interface cable that is more than 18 inches long.

4.1.4 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-7 Standard.

This drive is ship ped wi th S. M.A.R. T. features disab led. You must have a r ecent BIOS or so ft ware 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
