1.5 Seek time
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.
•
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 cylind er an d b ac k t o th e fi rst dat a
cylinder. The full-stroke typic al v al ue is determined by averaging 100
full-stroke seeks in both directions.

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 pag e 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 electron ics are active. Seek mode pow er 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 worstcase information.
Read/Write power an d current are me asured with t he heads on trac k,
based on a 16-sector write followed by a 32-msec delay, then a 16-sector
read followed by a 32-msec delay.
Page 17
Medalist 17242, 13032, 10232, 8422 and 4312, Rev. A9
Operating power and cu rrent are measured using 40 percent random
seeks, 40 perce nt read /write mode (1 wr ite f or e ach 10 reads ), and 20
percent drive inactive.
Idle mode power is measur ed with the drive up to speed, with servo
electronics active, and with the heads in a random track location.
During Standby mode, the drive accepts commands, but the drive is not
spinning, and servo and read/write electronics are in power-down mode.

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, th e dri ve is expec ted to op er ate with a ma xi mum
of 100 mV peak-to-peak square-wave injected noise at up to 10 MHz.
Note.
Equivalent resis tance is calcu lated by dividing the nomina l voltage 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
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:
commands and returns to Active mode any time disc access is
necessary.
. The drive is in Active mode during the read/write and seek
. The buffer remains enabled, and the drive accepts all
Standby mode
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
commands and returns to Active mode any time disc access is necessary.
. The drive enters Standby mode when the host sends a
Page 19
Medalist 17242, 13032, 10232, 8422 and 4312, Rev. A11
Sleep mode. The drive enters Sleep mode after receiving a Sleep
command from the host. 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 rec eiving a reset, the driv e 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, 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 a ny drive activity is required , the drive makes a
transition to Standb y mode. In both Idle and Standby mod e, the drive
accepts all commands and r etur ns to Ac tive mode when disc access is
necessary.

1.8.5 Shock
During shock tests, the drive was 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 document when subjected to a maximum op erating shock of 63 Gs (ba sed
on half-sine shock puls es of 2 msec). Shocks are not to b e 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 subsequently put into operation is 300 Gs (based on a nonrepetitive half-sine
shock pulse of 2 msec duration). Shock pulses are defined by MIL-STD202F.
1.8.6 Vibration
During vibration te sts, the drive was 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
experience while mee ting the performance sta ndards specified in this
document.

The following table lis ts the maximum nonoperating v ibration that the
drive may experience without incurring physical damage or degradation
in performance when subsequently put into operation.
5–22 Hz0.20-inch displacement (peak to peak)
22–350 Hz 5.0 Gs acceleration (zero to peak)
1.9 Drive acoustics
Drive acoustics were measu red as overall A-weighted ac oustic 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.
For the Seek mode, the drive was placed in seek only. Currently for these
drives, the approximate number of seeks per second is 26.6. The number
of seeks per second is defined by the following equation:
Number of seeks per second = 0.4 / (average latency + average access time)

1.12 Agency certification
1.12.1 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.
1.12.2 Electromagnetic Compatibility
Hard drives that display the CE marking comply with European Unio n
requirements specified in Electromagnetic Compatibility Directives.
Testing is performed to standards EN50082-1 and EN55022-B.
Seagate uses an independent laboratory to confirm compliance with the
EC directives speci fied in t he previous p aragrap h. Drives are tested in
representative end-user systems. Although CE-marked Seagate drives
comply with the dir ectives when used in the t est systems, we cannot
guarantee that all sy stems will c omply with the d irectives. Th e 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 manuf acturers and system integrato rs should confirm
EMC compliance and provide CE marking for their products.
Australian C-Tick
If these models have the C-Tick marking, they comply with the Australia/
New Zealand Standard AS/NZS 3548 1995 and meet the Electrom agnetic Compatibility (EMC) Framework requirements of Australia’s Spectrum Management Agency (SMA).

2.2 Jumper settings
2.2.1 Master/slave configuration
You must establish a master/slave relationship between two drives that
are attached to a single AT bus. You can configure a drive as a master
or slave by setting the master/slave jumpers, shown in Figure 2 on page
19.
These drives support mas ter /s lave c on f ig urati on u si ng t he c abl e s el ect
option. This requi res a special daisy-chai n cable that grounds pin 28
(CSEL) on one of its two drive connectors. If you attach the drive to the
grounded CSEL conn ector, i t is a ma ster . If y ou atta ch the drive to th e
ungrounded CSEL con nector, it is a sl ave. To us e this optio n, the h ost
system and both drives must support cable select, and both drives must
Page 26
18Medalist 17242, 13032, 10232, 8422 and 4312, Rev. A
be configured for c able select. To con figure this drive for cabl e select,
install a jumper as shown in Figure 2.
For the master drive to recognize the slave drive using the DASP– signal,
the slave drive must assert the DASP– signal at power up, and the
master drive must monitor DASP– at power up.
2.2.2 Alternate capacity jumper
Some older computers may “hang” if their BIOS detects a hard drive that
has more than 4,092 cyl inders at sta rtup. To allow th ese compu ters to
recognize the ST317242A, ST313032A, ST310232A, ST38422A or the
ST34312A, these drive s include a capac ity-limiting jum per, which sets
the drive’s default translation geometry to 4,092 cylinders. This limits the
drive’s capacity to 2.1 Gbytes, unless third-party software is used.
2.3 Ultra ATA/66 cable
An 80-conductor 40-pin cable is required to run Ultra DMA mode 3 and
4. This cable uses even-numbered conductors connected to the ground
pins to improve signal integrity.
Note.
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 (b it 1 3 of w or d
93 in the Identify drive parameter block).

2.4 Drive mounting
You can mount the drive in any orientation using four screws in the sidemounting holes or four screws in the bottom-mounting holes. See Figure
3 on page 20 for drive mounting dimensions.
Important mounting precautions:
•
Allow a minimum clearanc e of 0.030 inches (0.76 mm) around the
entire perimeter of the drive for cooling.
•
Use only 6-32 UNC mounting screws.
•
The screws should be inserted no more than 0.22 inch (5.58 mm) into
the bottom mounting holes and no more than 0.20 inch (5.0 mm) into
the side mounting holes.
•
Do not overtighten the mou nti ng s cre ws (m ax im um t orque : 3 i nc h- lb,
0.34 N.m, 3.45 kgf.cm) .
•
Do not use a drive interface cable that is more than 18 inches
(457 mm) long.

The following commands contain drive-specific features that may not be
described in the
Draft ATA-4 Standard
.
3.2.2 Identify Drive command
The Identify Drive command (command code ECH) transfer s information
about the drive to the host following power up. The data is organized as
a single 512-byte bl ock of data, whose contents are shown in the tabl e
below. All reserved bits or words should be set to zero. Parameters listed
with an “x” are drive-specific or vary with the state of the drive. See drive
specifications in Section 1 of this manual for default parameter settings.
Note.
If the alternate capacity j umper is install ed on these drives , the
drive capacity is reduced in word 1 to 4,092 cylinders.

3.2.3 Set Features command
This command control s the im pl eme ntati on of v ariou s f eatures that the
drive supports. When the drive receives this command, it sets BSY,
checks the contents of the Features register, clears BSY and generates
an interrupt. If the value in the register does not represent a feature that
the drive supports, th e command is aborted . Power-on d efault has the
read look-ahead and write caching features enabled. Th e acceptable
values for the Features register are defined as follows:

At power-on, or after a hardware reset, the default values of the features
are as indicated above. A softwa re reset also changes the fea tures to
default values.
3.2.4 S.M.A.R.T. commands
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
that are suscep tible to degradation over time. If self-monitor ing determines
that a failure is likely, S.M.A.R.T. makes a status report available to the
host. Not all failur es are predi ctable. S.M.A.R. T. predict ability is lim ited to
the attributes the drive can monitor . For more information on S.M.A.R.T.
commands and implementation, see the
Draft ATA-4 Standard.
These drives are shipped with S.M.A .R.T. featur es disa bled. You mus t
have a recent B IOS or software pac kage that supports S.M.A.R.T. to
enable the feature. The table below shows the S.M.A .R.T. command
codes that these drives use.
