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

• Full-stroke seek time is one-half the time needed to seek from the first

data cylinder to the m ax imu m d ata cy l inder an d b ac k t o th e fir st dat a
cylinder. The full-stro ke t ypic al v alue is dete rm in ed by ave ragi ng 10 0
full-stroke seeks in both directi on s.

Note. These drives are designed to meet the seek times represente d

in this manual consis tently. Phys ical seeks, r egardless of mode

6 ST320014A Product Manual, Rev. D

(such as track-to-track and average), are expected to meet or
exceed the noted values. How ever, due to the man ner in which
these drives are formatted, benchmark tests that include com
mand overhead or meas ure logical seeks may pr oduce results
that vary from these specifications.

1.7 Power specifications

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

1.7.1 Power consumption

Power requirements f or the drives are listed in the table on page 9.
Typical power measurements are based on an average of drives tested,
under nominal conditions, using 5.0V 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 reaches operating speed.

• Seek Mode

The read/write actuator arm moves in a random seek mode, with 80%
of the time spent seeking rand omly among all the logic al bloc ks, and
20% of the time idle. The current is measured over a 10-second period.
No data is read or written during this test.

-

• Read/Write power and current

Read/write power is me asured with the heads on track, ba sed on a
16-sector write followed by a 32-msec delay, then a 16-sector read
followed by a 32-msec delay.

• Operating power and current

The read/write actuator arm moves in a random read/write mode, with
80% of the time spent seeking, reading, and writing randomly among
all the logical blocks, and 20% of the time idle. The current is measured
over a 10-second period.

• Idle mode power

Idle mode power is measur ed with the driv e up to speed, with s ervo
electronics active and with the heads in a random track location.

• Standby mode

During Standby mode , the driv e accep ts comma nds, but the drive is
not spinning, and t he servo and read/write electr onics are in p ower­down mode.

• 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
Immediate command. If the hos t has set the sta ndb y timer, the drive
can also enter Standby mo de automatical ly after the driv e has been
inactive for a specifia ble length of time. The standby ti mer delay is

the input shock appli ed at the drive mounting screws. Sh ock may be
applied in the X, Y or Z axis.

1.8.5.1 Operating shoc k

These drives comply with the performance levels specified in this docu­ment when subjected to a maximum op erating shock of 63 Gs (ba sed
on half-sine shock p ulses of 2 msec). Sh ocks should not be repe ated
more than two times per second.

1.8.5.2 Nonoperating shock

The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when subse
quently put into operation is 350 Gs (based on nonrepetitive half-sin e
shock pulses of 1 and 2 msec duration).

1.8.6 Vibration

22–350 Hz 0.5 Gs acceleration (zero to peak)
351–500 Hz 0.25 Gs acceleration (zero to peak)

1.8.6.2 Nonoperating vibration

The following table lis ts the maximum nonoperatin g vibration that the
drive may experience without incurring physical damage or degradation
in performance when subsequently put into operation.

5–21 Hz 0.2-inch displacement (peak to peak)
22–350 Hz 5.0 Gs acceleration (zero to peak)
351–500 Hz 1.0 Gs acceleration (zero to peak)

1.9 Drive acoustics

Drive acoustics are measured as overall A-weighted acoustic sound
power levels (no pure tones). All measurements are generally consistent
with ISO document 7779. Sound power measurements were taken
under essentially free-field conditions over a reflecting plane. For all
tests, the drive was oriented with the cover facing upward.

Note. For seek mode tests, the drive was 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)

2.0 Configuring and mounting the drive

This section conta in s th e s pec if ic ati ons and instruction s for c on figuring
and mounting the drive.

2.1 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:

• The SeaShell™ replaces electrostatic discharge (ESD) bags. The

SeaShell package is a shock-ribbed, transparent clamshell enclosure
that limits a drive’s exposure to ESD and also protects against external
shocks and str esses. Th e design pe rmits atta ching cab les, softwar e
loading and label/barc ode scanning with out removing the dri ve from
the SeaShell. This minimizes handling damage. Keep the drive in the
SeaShell package until you are ready to install it.

• Before handling the drive, put on a grounde d wrist strap, or ground

yourself frequentl y by touching the metal chas sis of a com puter 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, anti static surfac e until y ou moun t

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 factory­installed labels contain information needed to service the drive. Other
labels are used to seal out dirt and contamination.

ST320014A Product Manual, Rev. D 17

2.2 Breather filter hole precautions

This section contains information regarding the precautions which
should be taken regarding the breather filte r hole in Seagate har d disc
drives. Proper p recautions should be taken to ens ure full function ality
and prevent possible damage to the drive.

Breather Hole

Do not cover

or seal.

Figure 2. 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

If this hole is cov ered, sealed, or penetrated by any object, the drive
reliability may be compromised and could lead to permanent damage—
doing so voids the warranty.

2.3 Jumper settings

2.3.1 Master/slave configuration

The options jumper block shown in Figure 2 is used to configure the drive
for operation. It is the 8-pin dual header between the interface connector
and the power connecto r. Use the following settings to c onfigure 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.

Set a jumper on pins 5 and 6 a nd a jumper o n pins 7 and 8. Use this
jumper s etting only if the drive does not work as a master with no jumpers
installed.

2.3.2 Cable-select option

Computers that use cable-select determine the master and slave drives
by selecting or dese lecting p in 28, CSEL, on th e interfac e bus. Mas ter
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
3 on page 18. Refer to your computer manual to determine whether your
computer supports this option.

2.3.3 Ultra ATA/100 cable

An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode
4 and mode 5. This cabl e uses even -numbered c onductors connected
to the ground pins to improve signal integrity.

Notes:

1. The drive supports both host and drive cable detection. The host

detects the 80-conductor cable by sampling pin 34, CBLID–, on
the interface bus. The drive detects the 80-cond uctor 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).

2. When using a 4 0-pin 80 -conductor cable, att ach th e blue con-
nector to the motherboard, the black connector to the master
drive, and the grey connector to the slave.

2.1 Drive mounting

You can mount the drive in any orientation using four screws in the side­mounting holes or four screws in the bottom-mounting holes. See Figure
3 for drive mounting dimensions. Follow these important mounting
precautions when mounting the drive:

• Allow a minimum clearanc e of 0.030 inches (0.76 mm) around the

entire perimeter of the drive for cooling.

• Use only 6-32 UNC mounting screws. Insert the screws no more than

0.20 inch (5.08 mm) into the bottom mounting holes and no more than

0.14 inch (3.55 mm) into the side mounting holes.

• 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.

3.1.4 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 pred etermined drive attributes
that are suscepti ble 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 failure s are predi ctable. S .M.A.R.T. predictabi lity is limited t o
the attributes the drive can monitor. For more information on S.M.A.R.T.
