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 t o th e m ax imu m d ata cy l ind er and back to the fi r st dat a
cylinder. The full-s tro ke t ypic al v al ue is determined by averagi ng 10 0
full-stroke seeks in both directions.

6 ST310014ACE Product Manual, Rev. B

Note. These drives are design ed to meet the seek times represe nted

in this manual con sistently. Phy sical seeks , regardless of mode
(such as track-to-track and average), are expected to meet or
exceed the noted value s. However, due to the manner in whi ch
these drives are formatted, benchmark tests tha t include com­mand overhead or m easure logical seeks may pr oduce results

that v ary from these specific ations.

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 for 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 see ki ng ran dom ly amo ng a ll th e lo gi ca l bl ocks , an d
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 meas ured with the heads on track, based on a
16-sector write fol lowed by a 32-msec delay, the n 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 meas ured with the dri ve up to s peed, with servo
electronics active and with the heads in a random track location.

• Standby mode

During Standby m ode, the dri ve accep ts command s, but the dri ve is

1.7.2 Conducted noise

Input noise ri ppl e i s measured at the ho st sy s tem powe r su ppl y ac ro ss
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-peak square-wave injected noise at up to 10 MHz.

• Using 5-volt power , th e dr i ve is ex pec ted to op er ate with a maximum

of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz.

Note. Equivalent r esistan ce is cal culated by divi ding the nominal volt-

age by the typical RMS read/write current.

1.7.3 Voltage tolerance

Voltage tolerance (including noise): 5V ± 5% and 12V ± 10%

1.7.4 Power-management modes

The drive provides programmable power management to provide great­er energy efficie ncy. In mos t system s, y ou can c ontrol po wer m anage­ment through the system setup program. The drive features the following
power-management modes:

Power Modes 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
Immediate comman d. If the host has set the sta ndby ti mer, the dri ve
can also enter Standb y mode automa tically after the driv e has been
inactive for a speci fiable length of time. The standby timer delay is

ST310014ACE Product Manual, Rev. B 9

established using a Standby 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 enters Sleep mode after rec eiving a Slee p command from
the host. In Sleep mode, the dr ive buffer is disabled, the heads ar e
parked and the spindl e is at rest. The driv e leaves Sl eep mode after
it receives a Hard Reset or Soft Reset from the host. After receiving a
reset, the drive exits Sl eep mode and enters 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 beg ins counting down from its
specified delay times to zero. If the standby timer reaches zero before
any drive activi ty is re quired, the driv e make s a tran sition to S tan dby
mode. In both Idle and Standby mode, the drive accepts all commands
and returns to Active mode when disc access is necessary.

1.8 Environmental tolerances

1.8.1 Ambient temperature

Ambient temperature is define d a s the tem perature of the envir on men t
immediately surrounding the drive. Actual drive case temperature should
not exceed
ommended measurement locations are shown in Figure 3 on page 18.

1.8.5 Shock

All shock specifications assume that the drive is mounted securely with
the input shock ap plied at the drive mounting screws. Shock may be
applied in the X, Y or Z axis.

1.8.5.1 Operating shock

These drives comply with the performance levels specified in this docu­ment when subjected to a maximu m operating shock of 63 Gs (based
on half-sine sh ock pulses of 2 msec) . Shocks should not be r epeated
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 subse­quently put into operation is 350 Gs (based on nonrepetitive half-sin e
shock pulses of 1 and 2 msec duration).

1.8.6 Vibration

All vibration spe cifications assume that the dri ve is mounted securely
with the input vibratio n applied at the drive mounti ng screws. V ibratio n
may be applied in the X, Y or Z axis.

ST310014ACE Product Manual, Rev. B 11

1.8.6.1 Operating vibration

The following table lists the maximum vibratio n levels that the drive may expe­rience while meeting the performance stand ards specified in this d ocument.

5–21 Hz 0.02-inch displacement (peak to peak)
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 tabl e lists the maximum nonopera ting 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 dri ve 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)

motherboard, power supply, etc.) does comply with the limits for a Class
B computing de vice, pursuant to S ubpart J , Part 15 of the FCC rul es.
Operation with noncerti fied as semblies is likel y to result in interfere nce
to radio and television reception.

Radio and television interference. This equipment generates and
uses radio frequency energy and if not installed and used in strict
accordance with the manufacturer’s instructions, may cause interfer­ence to radio and television reception.

This equipment is designed to provide reasonable protection against
such interference in a residential installation. However, there is no
guarantee that inte rference will not occur in a parti cular installation. If
this equipment does cause interference to radio or television, which can
be determined by turning the equipment on and off, you are encouraged
to try one or more of the following corrective measures:

• Reorient the receiving antenna.

• Move the device to one side or the other of the radio or TV.

• Move the device farther away from the radio or TV.

• Plug the computer into a different outlet so that the receiver and

computer are on different branch outlets.

If necessary, you should consult your dealer or an experi enced radio/
television technician for additional suggestions. You may find helpful the

2.0 Configuring and mounting the drive

This section c onta in s th e spec ifications and in structions fo r con 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 stress es. The design permits attaching cables, softw are
loading and label /barcode scannin g without removing the dri ve from
the SeaShell. This minimizes handling damage. Keep the drive in the
SeaShell package until you are ready for installation.

• Before handling the driv e, put on a grounded wrist stra p, or ground

yourself freque ntly by touch ing the metal chassis of a c omputer tha t
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 dr ive on a padded, antista tic su rfac e until you 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.

2.2 Jumper settings

2.2.1 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 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.

2.2.2 Cable-select option

Computers that use cable-select determine the master and slave drives
by selecting or de selecting p in 28, CSEL, on the inter face bus. M aster
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
2 on page 16. Refer to your computer manual to determine whether your
computer supports this option.

2.2.3 Ultra ATA/100 cable

An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode
4 and mode 5. This c able uses even -number ed conductors connecte d
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 bu s. The dri ve detec ts th e 80- conduc tor cab le 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 for drive mounting dimensions. Follow these important mounting
precautions 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. 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.

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 deg radation over time. If self-monitoring determin es
that a failure is likely, S.M.A.R.T. makes a status report available to the
host. Not all fai lures are p redicta ble. S.M.A. R.T. pred ictabilit y is limited t o
