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 maximum data cylinder and back to the first data
cylinder. The full-stroke typical value is determined by averaging 100
full-stroke seeks in both directions.

ST310014ACE Product Manual, Rev. D
Note. These drives are designed to meet the seek times represented
in this manual consistently. 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 com-
mand overhead or measure logical seeks may produce 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 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 seeking randomly among all the logical blocks, 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 measured with the heads on track, based 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 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

1.7.2 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-peak 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 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 great-
er energy efficiency. In most systems, you can control power manage-
ment through the system setup program. The drive features the following
power-management modes:

• 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 host 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 timer delay is
ST310014ACE Product Manual, Rev. D

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 receiving a Sleep command from
the host. In Sleep mode, the drive 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 Soft Reset from the host. After receiving a
reset, the drive exits Sleep 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 begins counting down from its
specified delay times to zero. If the standby timer reaches zero before
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.
1.8 Environmental tolerances
1.8.1 Ambient temperature
Ambient temperature is defined as the temperature of the environment
immediately surrounding the drive. Actual drive case temperature should
not exceed 65°C (149°F) within the operating ambient conditions. Rec-
ommended measurement locations are shown in Figure 4 on page 19.
Above 1,000 feet (305 meters), the maximum temperature is derated
linearly to 112°F (44°C) at 10,000 feet (3,048 meters).

1.8.5 Shock
All shock specifications assume that the drive is mounted securely with
the input shock applied 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 docu-
ment when subjected to a maximum operating shock of 63 Gs (based
on half-sine shock pulses of 2 msec). Shocks should not be repeated
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-sine
shock pulses of 1 and 2 msec duration).
1.8.6 Vibration
All vibration specifications assume that the drive is mounted securely
with the input vibration applied at the drive mounting screws. Vibration
may be applied in the X, Y or Z axis.

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)

This equipment is designed to provide reasonable protection against
such interference in a residential installation. However, there is no
guarantee that interference will not occur in a particular 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 experienced radio/
television technician for additional suggestions. You may find helpful the
following booklet prepared by the Federal Communications Commis-
sion: How to Identify and Resolve Radio-Television Interference Prob-
lems. This booklet is available from the Superintendent of Documents,
U.S. Government Printing Office, Washington, DC 20402. Refer to pub-
lication number 004-000-00345-4.

2.0 Configuring and mounting the drive
This section contains the specifications and instructions for configuring
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 stresses. The design permits attaching cables, software
loading and label/barcode scanning without removing the drive from
the SeaShell. This minimizes handling damage. Keep the drive in the
SeaShell package 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-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.

2.2 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 taken to ensure full functionality
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 covered, 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
17
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 connector. Use the following settings to configure the
drive as a master or a slave.
Masteror 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 and a jumper on pins 7 and 8. Use this
jumper setting only if the drive does not work as a master with no jumpers
installed.

ST310014ACE Product Manual, Rev. D
2.3.2 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
3 on page 17. 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 cable uses even-numbered conductors 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-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).
2. When using a 40-pin 80-conductor cable, attach the blue con-
nector to the motherboard, the black connector to the master
drive, and the grey connector to the slave.
ST310014ACE Product Manual, Rev. D

2.1 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 holes. See Figure
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
thataresusceptibletodegradationovertime. Ifself-monitoringdetermines
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-Rev 6 Standard.
