2.6 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.

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.

2.8 Power specifications

The drive receives DC power (+5V and +12V) through a four-pin standard drive power connector.

2.8.1 Power consumption

Power requirements for the drives are listed in the table on page 13. 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 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.

2.8.2 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.

2.8.4 Power-manag ement 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 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.

2.14 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 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

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 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.

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 all ed labels fr om the drive or cover the m wi th additio nal labels. Rem oval voi ds
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 filter hole precautions

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 ta ken 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 Jumper sett ings

Circuit Board

3.3.1 Master/slave configuration

The options jumper block shown in Figure 4 is used to configure the drive for operation. It is the 8-pin dual
header between the interface connector and the power connector. Use the following settings to configure the
drive as a master or a slave.

Master or single drive. The drive is configured at the factory for a master or single-drive operation with a
jumper set on pins 7 and 8.

Drive as slave. Remove all jumpers.
Drive as master with a non-ATA-compatible slave.

Use this jumper setting only if the drive does not work as a master with no jumpers installed.

Figure 4 Master/slave jumper settings

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 36 for more details on the Set Features command.

Figure 5 Ultra ATA cable connectors

Note. The drive supports bo th host and drive cabl e det ection. T he host det ect s the 80-co nducto r 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.

).

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.

You can use a daisy-chain cable to connect two drives to a single AT host bus. For detailed information about
the ATA interface, refer to the draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-7), NCITS
T13 1410D, subsequently referred to as the Draft ATA-7 Standard.

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.

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 w ith S. M.A.R .T. features disab led. You must have a r ecent 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.
