2.7 Seek time
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using
drive diagnostics. The specifications below 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.
*Measured in performance mode
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 exceed the noted values.
However, due to the manner in which these drives are formatted, benchmark tests that include command
overhead or measure logical seeks may produce results that vary from these specifications.

2.9 Power specifications
The drive receives DC power (+5V) through the interface connector.
2.9.1 Power consumption
Power requirements for the drives are listed in the Table 2 on page 8. Typical power measurements are based
on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient tempera-
ture.
• Spinup power
Spinuppowerismeasuredfromthetimeofpower-ontothetimethatthedrivespindlereachesoperatingspeed.
• Seek mode
During seek mode, the read/write actuator armmoves toward a specific position on the disc surface and does
not execute a read or write operation. Servo electronics are active. Seek mode power is measured based on
three random seek operations every 100 msecs. This mode is not typical.
•Read/write power and current
Read/write power is measured with the heads on track, based on three 63 sector read or write operations
every 100 msecs.
• 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 idle mode.
• 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.
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and
power to operational levels.

2.9.2 Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5 volt line.
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 voltage by the typical RMS read/write
current.
2.9.3 Voltage tolerance
Voltage tolerance (including noise):
5V ± 5%

2.9.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems,
you can control power management 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
specifiablelengthoftime.ThestandbytimerdelayisestablishedusingaStandbyorIdle command.InStandby
mode, the drive buffer is in Self Refresh Low Power mode, 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 in Self Refresh Low Power mode, 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.

These drives comply with the performance levels specified in this document when subjected to a maximum
operating shock of 250 Gs based on half-sine shock pulses of 2 msec. Shocks should not be repeated more
than two times per second.
2.10.5.2 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 800 Gs based on a nonrepetitive half-sine shock pulse
of 2 msec duration.
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 900 Gs based on a nonrepetitive half-sine shock pulse
of 1 msec duration.
The nonoperating shock level that the drive can experience without incurring physical damage or degradation
in performance when subsequently put into operation is 400 Gs based on a nonrepetitive half-sine shock pulse
of 0.5 msec duration.
2.10.6 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.
2.10.6.1 Operating vibration
The following table lists the maximum vibration levels that the drive may experience while meeting the perfor-
mance standards specified in this document.
2.10.6.2 Nonoperating vibration
The following table lists the maximum nonoperating vibration that the drive may experience without incurring
physical damage or degradation in performance when subsequently put into operation.
5–500 Hz: 1.0 Gs (0 to peak). Max displacement may apply below 10 Hz.
5–500 Hz: 5.0 Gs (0 to peak). Max displacement may apply below 22 Hz.

2.11 Acoustics
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea-
surements are consistent with ISO document 7779. Sound power measurements are taken under essentially
free-field conditions over a reflecting plane. For all tests, the drive is oriented with the cover facing upward.
Note. Forseek modetests,thedriveis placedinseek modeonly.Thenumberofseekspersecondisdefined
by the following equation:
(Number of seeks per second = 0.4 / (average latency + average access time)
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and
power to operational levels.
2.12 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in
performance when subjected to the radio frequency (RF) environments defined in the following table:

2.13 Reliability
2.14 Agency certification
2.14.1 Safety certification
The drives are recognized in accordance with UL 1950 and CSA C22.2 (950) and meet all applicable sections
of IEC950 and EN 60950 as tested by TUV North America.
2.14.2 Electromagnetic compatibility
Hard drives that display the CE mark comply with the European Union (EU) requirements specified in the Elec-
tromagnetic Compatibility Directive (89/336/EEC). Testing is performed to the levels specified by the product
standards for Information Technology Equipment (ITE). Emission 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 properly 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.
