1.6 Seek times
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.
•Averageseektimeisatruestatisticalrandomaverageofatleast5,000
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.
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%ofthetimeidle.Thecurrentismeasuredovera10-secondperiod.
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
allthelogicalblocks,and20%ofthetimeidle.The currentismeasured
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
not spinning, and the servo and read/write electronics are in power-
down mode.

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-
mentthroughthesystemsetupprogram.Thedrivefeaturesthefollowing
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

Idle Tracking Rotating Enabled

ST320014A 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 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
immediatelysurroundingthedrive.Actualdrivecasetemperatureshould
not exceed 65°C (149°F) within the operating ambient conditions. Rec-
ommended measurement locations are shown in Figure 3 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).

ment when subjected to a maximum operating shock of 63 Gs (based

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).

The following table lists the maximum vibration levels that the drive may
experience while meeting the performance standards specified in this
document.
1.8.6.2 Nonoperating vibration
The following table lists the maximum nonoperating vibration that the

1.9 Drive acoustics
Drive acoustics are measured as overall A-weighted acoustic sound
power levels(nopuretones).Allmeasurementsaregenerallyconsistent
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)
5–21 Hz 0.02-inch displacement (peak to peak)

1.12 Agency certification
1.12.1 Safety certification
The drive is recognized in accordance with UL 1950 and CSA C22.2
(950) and meets all applicable sections of IEC950 and EN 60950 as
tested by TUV North America.
1.12.2 Electromagnetic compatibility
Hard drives that display the CE mark comply with the European Union
(EU) requirements specified in the Electromagnetic Compatibility Direc-
tive (89/336/EEC). Testing is performed to the levels specified by the
product standards for Information Technology Equipment (ITE). Emis-
sion levels are defined by EN 55022, Class B and the immunity levels
are defined by EN 55024.
Seagate uses an independent laboratory to confirm compliance with the
EC directives specified in the previous paragraph. Drives are tested in
representative end-user systems. Although CE-marked Seagate drives
comply with the directives when used in the test systems, we cannot
guarantee that all systems will comply with the directives. The drive is
designed for operation inside a properly designed enclosure, with prop-
erly shielded I/O cable (if necessary) and terminators on all unused I/O
ports. Computer manufacturers and system integrators should confirm
EMC compliance and provide CE marking for their products.

(MIC) logo, it complies with paragraph 1 of Article 11 of the Electromag-
netic Compatibility control Regulation and meets the Electromagnetic
