SEAGATE ST38641A INSTALLATION GUIDE
Jumper settings
===============
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 to be
a master or slave by setting the master/slave jumpers.
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 becomes a master. If you
attach the drive to the ungrounded CSEL connector, it becomes a
slave. To use this option, the host system and both drives must
support cable select, and both drives must be configured for cable
select. To configure this drive for cable select, install a jumper.
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.
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 ST38641A, the ST36531A, the ST34321 or the
ST33221A, 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.
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. 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.
Note. If the alternate capacity jumper is installed on these drives,
the drive capacity is reduced in word 1 to 4,092 cylinders.

The drive will operate in all axis (6 directions).
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.
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.
- Do not insert the mounting screws more than 0.25 inches (6.25 mm)
into the mounting holes.
- Do not overtighten the mounting screws (maximum torque: 3 inch-lb).
- Do not use a drive interface cable that is more than 18 inches
long.
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 and 2. 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 regarding 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 Standard.

Drive specifications
--------------------
Unless otherwise noted, all specifications are measured under ambient
conditions, at 25*C, and nominal power. For convenience, the phrases
the drive and this drive are used throughout this manual to indicate
the ST38641A, ST36531A, ST34321A, ST33221A and the ST32110A.
Note. DOS systems cannot access more than 528 Mbytes on a drive
unless 1) the host system supports and is configured for LBA
addressing or for extended CHS addressing, 2) the host system
contains a specialized drive controller, or 3) the host system runs
BIOS translation software. Contact your Seagate (r) repre-sentative
for details.
LBA Mode
--------
When addressing either drive in LBA mode, all blocks (sectors) are
consecutively numbered from 0 to n - 1, where n is the number of
guaranteed sectors as defined above.
Supported CHS translation geometries
------------------------------------
These drives support any translation geometry that satisfies all of
the following conditions:
- Sectors per track - 63
- Heads - 16
The ST38641A logical cylinders are:
Logical cylinders=16,809,660

Interleave 1:1
Cache buffer (Kbytes) 128
Seek time
---------
All seek times are measured using a 486 AT computer (or faster) with
a 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.
Power Specifications
--------------------
The drive receives DC power (+5V or +12V) through a four-pin standard
drive power connector.
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.
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 the servo and read/write electronics are in power-down
mode.
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
voltage by the typical RMS read/write current.
Voltage tolerance
-----------------
Voltage tolerance (including noise): 5V 5% and 12V 10%
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.
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.
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.
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.
Operating shock
---------------
These drives comply with the performance levels specified in this
document when subjected to a maximum operating shock of 10.0 Gs
(based on half-sine shock pulses of 11 msec, as specified in
MIL-STD-202F).
Shocks are not to be repeated more than two times per second.
Nonoperating shock
------------------
The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when
sub-sequently put into operation is 75 Gs (based on nonrepetitive
halfsine shock pulses of 11 msec duration) or 200 Gs (based on
nonrepetitive halfsine shock pulses of 2 msec duration). Shock
pulses are defined by MIL-STD-202F.
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.
Operating vibration
-------------------
The following table lists the maximum vibration levels that the drive
may experience while meeting the performance standards specified in
this document.
5-22 Hz 0.20-inch displacement (peak to peak)
22-350 Hz 0.50 Gs acceleration (zero to peak)
Nonoperating vibration
----------------------
The following table lists the maximum nonoperating vibration that the
drive may experience without incurring physical damage or degradation
in performance when put into operation.
5-22 Hz 0.10-inch displacement (peak to peak)
22-350 Hz 5.0 Gs acceleration (zero to peak)
Drive acoustics
---------------
Drive acoustics are measured as overall A-weighted acoustic sound
power levels (no pure tones). All measurements are generally
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.
For the seeking mode, the drive is placed in seek only. The number of
seeks per second is defined by the following equation:
Number of seeks per second=0.4/(average latency+average access time)
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.
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
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.
Australian C-Tick
If this model has the C-Tick marking, it complies with the
Australia/New Zealand Standard AS/NZS3548 1995 and meets the
Electromagnetic Compatibility (EMC) Framework requirements of
Australia's Spectrum Management Agency (SMA).
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
described 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
interference 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
Commission:
How to Identify and Resolve Radio-Television Interference Problems.
This booklet is available from the Superintendent of Documents,
U.S. Government Printing Office, Washington, DC 20402. Refer to
publication number 004-000-00345-4.
Handling and static-discharge precautions
-----------------------------------------
After unpacking, and before installation, the drive may be exposed to
potential handling and electrostatic discharge (ESD) hazards. Observe
standard static-discharge precautions. A grounded wrist-strap is
preferred.
Handle the drive only by the sides of the head/disc assembly. Avoid
contact with the printed circuit board, all electronic components and
the interface connector. Do not apply pressure to the top cover of
the drive.
Always rest the drive on a padded antistatic surface until you mount
it in the host system.
S.M.A.R.T.
----------
S.M.A.R.T. provides nearterm failure prediction for disc drives.
When S.M.A.R.T. is enabled, the drive monitors predetermined drive
attributes that are susceptible to degradation over time. If
selfmonitoring determines 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.
