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.

 - These drives use MR recording heads and PRML technology, which
   provides the drives with increased areal density.


 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

 The ST36531A logical cylinders are:
     Logical cylinders=12,706,470

 The ST34321A logical cylinders are:
     Logical cylinders=8,404,830

 The ST33221A logical cylinders are:
     Logical cylinders=6,303,024

 The ST32110A logical cylinders are:
     Logical cylinders= 4,124,736


 Internal data-transfer rate (Mbits per second max) 140

 I/O data-transfer rate (Mbytes per second max) 16.6 (PIO mode 4 with
 IORDY) 16.6 (multiword DMA mode 2)

 33.3 (Ultra DMA mode 2)

 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.
