1.5 Seek time  
The measurements are taken with nominal power at 25°C ambient  
temperature. All times are measured using drive diagnostics. The spec-  
ifications 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 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  
exceed the noted values. Due to the manner in which these drives  
are formatted, however, benchmark tests that include command  
overhead or that 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 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,  
based on a 16-sector write followed by a 32-msec delay, then a 16-sector  
read followed by a 32-msec delay.  
 
Medalist 17242, 13032, 10232, 8422 and 4312, Rev. A  
9
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.  
During Standby mode, the drive accepts commands, but the drive is not  
spinning, and 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  
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. 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  
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.  
 
Medalist 17242, 13032, 10232, 8422 and 4312, Rev. A  
11  
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 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, 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.

ment when subjected to a maximum operating shock of 63 Gs (based  
on half-sine shock pulses of 2 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 300 Gs (based on a nonrepetitive half-sine  
shock pulse of 2 msec duration). Shock pulses are defined by MIL-STD-  
202F.

1.9 Drive acoustics  
Drive acoustics were measured as overall A-weighted acoustic 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).

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 Union  
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 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.  
Australian C-Tick  
If these models have the C-Tick marking, they comply with the Australia/  
New Zealand Standard AS/NZS3548 1995 and meet the Electromag-  
netic Compatibility (EMC) Framework requirements of Australia’s Spec-  
trum Management Agency (SMA).

1.12.3 FCC verification  
These drives are intended to be contained solely within a personal  
computer or similar enclosure (not attached as an external device). As  
such, each drive is considered to be a subassembly even when it is  
individually marketed to the customer. As a subassembly, no Federal  
Communications Commission verification or certification of the device is  
required.  
Seagate Technology, Inc. has tested this device in enclosures as de-  
scribed above to ensure that the total assembly (enclosure, disc drive,  
motherboard, power supply, etc.) does comply with the limits for a Class  
B computing device, pursuant to Subpart J, Part 15 of the FCC rules.  
Operation with noncertified assemblies is likely to result in interference  
to radio and television reception.  
Radio and Television Interference. This equipment generates and  
uses radio frequency energy and if not installed and used in strict  
accordance with the manufacturer’s instructions, may cause interfer-  
ence to radio and television reception.  
This equipment is designed to provide reasonable protection against  
such interference in a residential installation. However, there is no  
guarantee that interference will not occur in a particular installation. If  
this equipment does cause interference to radio or television, which can  
be determined by turning the equipment on and off, you are encouraged  
to try one or more of the following corrective measures:  
Reorient the receiving antenna.  
Move the device to one side or the other of the radio or TV.  
Move the device farther away from the radio or TV.  
Plug the computer into a different outlet so that the receiver and  
computer are on different branch outlets.  
If necessary, you should consult your dealer or an experienced radio/  
television technician for additional suggestions. You may find helpful the  
following booklet prepared by the Federal Communications Commis-  
sion: How to Identify and Resolve Radio-Television Interference Prob-  
lems. This booklet is available from the Superintendent of Documents,  
U.S. Government Printing Office, Washington, DC 20402. Refer to pub-  
lication number 004-000-00345-4.

2.0 Drive mounting and configuration  
2.1 Handling and static-discharge precautions  
17  
After unpacking, and before installation, the drive may be exposed to  
potential handling and electrostatic discharge (ESD) hazards. Observe the  
following standard handling and static-discharge precautions:  
Caution:  
Keep the drive in its static-shielded bag until you are ready to complete  
the installation. Do not attach any cables to the drive while it is in its  
static-shielded bag.  
Before handling the drive, put on a grounded wrist strap, or ground  
yourself frequently by touching the metal chassis of a computer that  
is plugged into a grounded outlet. Wear a grounded wrist strap  
throughout the entire installation procedure.  
Handle the drive by its edges or frame only.  
The drive is extremely fragile—handle it with care. Do not press down  
on the drive top cover.  
Always rest the drive on a padded, antistatic surface until you mount  
it in the computer.  
Do not touch the connector pins or the printed circuit board.  
Do not remove the factory-installed labels from the drive or cover them  
with additional labels. Removal voids the warranty. Some factory-  
installed labels contain information needed to service the drive. Other  
labels are used to seal out dirt and contamination.  
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 master/slave configuration using the cable select  
option. This requires a special daisy-chain cable that grounds pin 28  
(CSEL) on one of its two drive connectors. If you attach the drive to the  
grounded CSEL connector, it is a master. If you attach the drive to the  
ungrounded CSEL connector, it is a slave. To use this option, the host  
system and both drives must support cable select, and both drives must  
 
18  
Medalist 17242, 13032, 10232, 8422 and 4312, Rev. A  
be configured for cable select. To configure this drive for cable 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 cylinders at startup. To allow these computers to  
recognize the ST317242A, ST313032A, ST310232A, ST38422A or the  
ST34312A, these drives include a capacity-limiting jumper, 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 (bit 13 of word  
93 in the Identify drive parameter block).

2.4 Drive mounting  
You can mount the drive in any orientation using four screws in the side-  
mounting 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 clearance 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 mounting screws (maximum torque: 3 inch-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.

3.0 ATA interface  
These drives use the industry-standard ATA task file interface that  
supports 16-bit data transfers. It supports ATA programmed input/output  
(PIO) modes 0, 1, 2, 3 and 4; multiword DMA modes 0, 1 and 2; and  
Ultra DMA modes 0, 1, 2, 3 and 4. The drive also supports the use of  
the IORDY signal to provide reliable high-speed data transfers.  
You can use a daisy-chain cable to connect two drives to a single AT  
host bus. For detailed information about the ATA interface, refer to the  
draft of AT Attachment with Packet Interface Extension (ATA/ATAPI-4),  
NCITS T13 1153D, subsequently referred to as the Draft ATA-4 Stan-  
dard.

3.2.2 Identify Drive command  
The Identify Drive command (command code ECH) transfers information  
about the drive to the host following power up. The data is organized as  
a single 512-byte block of data, whose contents are shown in the table  
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 jumper is installed on these drives, the  
drive capacity is reduced in word 1 to 4,092 cylinders.

3.2.3 Set Features command  
This command controls the implementation of various features 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, the command is aborted. Power-on default has the  
read look-ahead and write caching features enabled. The acceptable  
values for the Features register are defined as follows:  
02H  
03H  
Enable write cache (default).  
Set transfer mode (based on value in Sector Count register).  
Sector Count register values:  
00H Set PIO mode to default (PIO mode 2).  
01H Set PIO mode to default and disable IORDY  
(PIO mode 2).  
08H PIO mode 0  
09H PIO mode 1

At power-on, or after a hardware reset, the default values of the features  
are as indicated above. A software reset also changes the features 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  
thataresusceptibletodegradationovertime. Ifself-monitoringdetermines  
that a failure is likely, S.M.A.R.T. makes a status report available to the  
host. Not all failures are predictable. S.M.A.R.T. predictability is limited 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. features disabled. You must  
have a recent BIOS or software package 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.
