1.5 Seek time
All seek times are measured using a 486 AT computer (or faster) with
an 8.3 MHz I/O bus. The measurements are taken with nominal power
at 25°C ambient temperature. All times are measured using drive diag-
nostics. 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.
•Averageseektimeis atruestatistical random averageofatleast5,000
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 consistently meet the seek times rep-
resentedinthismanual. Physicalseeks,regardless ofmode (suchas
track-to-trackandaverage)areexpectedtomeetorexceedthenoted
values.However,duetothemannerinwhichthesedrivesareformat-
ted, benchmark tests that include command overhead or measure
logicalseeks mayproduce resultsthatvaryfromthesespecifications.

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
During seek mode, the read/write actuator arm moves toward a
specific position on the disc surface and does not execute a read or
write operation. Servo electronics are active. Seek mode power rep-
resents the worst-case power consumption, using only random seeks
with read or write latency time. This mode is not typical and is provided
for worst-case information.
•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
Operating power is measured using 40 percent random seeks, 40
percent read/write mode (1 write for each 10 reads) and 20 percent
drive inactive.
•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.Thedrivefeatures thefollowing
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
established using a Standby or Idle command. In Standby mode, the

ST34323A Family Product Manual, Rev. C 11
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 Active mode with all

•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. Inboth Idle andStandbymode, the drive acceptsall commands
and returns to Active mode when disc access is necessary.
1.8 Environmental tolerances
1.8.1 Ambient temperature
Note. Above 1,000 feet (305 meters), the maximum temperature is
derated linearly to 112°F (44°C) at 10,000 feet (3,048 meters).
Operating ambient temperature is defined as the temperature of
the environment immediately surrounding the drive.
1.8.2 Temperature gradient
Operating 5° to 55°C (41° to 131°F)
Nonoperating –40° to 70°C (–40° to 158°F)
Operating 20°C/hr (68°F/hour) max, without condensation
