1.4 Physical characteristics
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
diagnostics. 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.
•Averageseektime isatrue statisticalrandomaverageofatleast5,000
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
represented in this manual. Physical seeks, regardless of mode
(such as track-to-track and average) are expected to meet or
exceedthenotedvalues. Duetothemannerinwhichthesedrives
are formatted, however, benchmark tests that include command
overheador measurelogicalseeks may produceresultsthatvary
from these specifications.
1.6 Start/stop times
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 is measured from the time of power-on to the time that the
drive spindle reaches operating speed.
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 represents
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 are measured with the heads on track,
basedona16-sectorwritefollowedbya32-msecdelay,thena16-sector
read followed by a 32-msec delay.
Operating power and current are 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 is measured with the drive up to speed, with servo
electronics active, and with the heads in a random track location.
Power-on to Ready (sec) 10 (typical)
Standby to Ready (sec) 10 (typical)
Ready to spindle stop (sec) 12 (typical)

Medalist 10240, 7630, 5120, 2510 Product Manual, Rev. B 9
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 ± 8%
1.7.4 Power-management modes
These drives provide programmable power management to provide
greater energy efficiency. In most systems, you can control power
management through the system setup program. These Seagate drives
feature several power-management modes, which are summarized in
the following table and described in more detail below:
Active mode. Thedriveis inActivemodeduringtheread/writeandseek
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
heads are parked and the spindle is at rest. The drive accepts all
commandsandreturnstoActivemodeanytimediscaccessisnecessary.
Mode Heads Spindle Buffer
Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled

Medalist 10240, 7630, 5120, 2510 Product Manual, Rev. B 11
Sleep mode. The drive enters Sleep mode after receiving a Sleep
command from the host. Theheadsare parkedand the spindleisat rest.
Thedrive leaves Sleepmodeafterit receives aHardResetorSoftReset
from the host. After receiving a reset, the drive exits Sleep mode and
enters Active mode with all current translation parameters intact.
Idle and Standby timers. Each time the drive performs an Active
function(read,writeorseek),thestandbytimerisreinitializedandbegins
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
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.

1.8.4 Altitude
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 15.0 Gs (based
on half-sine shock pulses of 11 msec). Shocks are not to 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 75 Gs (based on nonrepetitive half-sine
shock pulses of 11 msec duration) or 200 Gs (based on nonrepetitive
half-sine shock pulses of 2 msec duration). Shock pulses are defined by
MIL-STD-202F).
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.
1.8.6.1 Operating vibration
The following table lists the maximum vibration levels that the drive may
