 Master/Slave configuration
 --------------------------
 Pins 1 and 2 and pins 3 and 4 on the options jumper block are used
 to configure the drive as the slave or as master with a slave
 present.

 One drive only
 The drive is configured at the factory for single-drive operation.
 No shunts aree placed on pins 1 and 2 or pins 3 and 4. The spare
 shunt on pins 2 and 4 does not affect drive operation.

 Drive as slave
 Place a shunt on pins 1 and 2.

 Drive as master with a slave present
 Place a shunt on pins 3 and 4.


 ATA master/slave compatibility
 ------------------------------
 You can extend the length of time the Seagate drive as master waits
 for the slave to responds before it reports the status of both drives
 to the host during a boot cycle. When a shunt is placed on pins 5 and
 6, the Seagate drive waits 30 seconds for the slave to signal that it
 is ready to give status. The default setting allows the slave five
 seconds to respond.


 Remote LED connection
 ---------------------
 Pins 11(-) and 12(+) on the options jumper block are used to connect
 the drive to a remote LED. The LED is polarized and can be damaged
 if connected incorrectly.

 It may be necessary to replace the current connector on the LED cable
 to fit the options jumper block. Use Seagate part number 13211-001 or
 an equivalent for the replacement connector.


 Cable-Select Option
 -------------------
 Computers that use the cable-select method for determining the master
 and slave drive do so by selecting or deselecting pin 28, CSEL, on
 the interface bus. The master and slave drives are determined by
 their physical position on the bus:

 - The drive is plugged into the I/O connector that carries the CSEL
   signal is the master.

 - The drive plugged into the I/O connector that does not carry the
   CSEL signal is the slave.

 To configure the drives for computers that use cable select:

 - Install shunts on pins 9 and 10.

 Power consumption
 -----------------
 The drives supports Active, Idle, Standby and Sleep power-management
 modes.

 Active mode
 -----------
 During the Active mode, the drive is involved in spinup, seeking or
 read/write activities.

 Spinup.
 Spinup mode is entered from the Standby mode. The drive brings the
 spindle and discs up to operating speed. Power in this mode is
 measured from power-on to the time the drive is ready for normal
 operation.

 Seeking.
 Seek mode is entered from Idle mode. The read/write heads are moved
 to a specific location on the disc surface in preparation for reading
 from or writing to the disc.

 Typical power is defined as the power average of executing random
 seeks with a 2-revolution (22.2 msec) dwell between Seek commands.
 Read/write. Read/write power and current are measured with the
 heads on track. The test cycle consists of writing 16 sectors
 followed by a 22.2 msec delay and reading 16 sectors followed by a
 22.2 msec delay.


 Idle mode
 ---------
 The motor is up to speed, the servo electronics are inactive and the
 heads are in the landing zone. A time delay is encountered when
 executing a command requiring disc access.

 The drive enters Idle mode when the host issues an Idle, Idle
 Immediate or Idle and Set Idle Timer command. The Idle timer is a
 Seagate-unique command, and is disabled by the factory.


 Standby mode
 ------------
 Standby mode is entered from the Idle mode. The drive is fully
 operational through the interface and accepts commands, but a latency
 will occur if any command received requires disc access or actuator
 movement. In Standby mode, the spindle is stopped, the heads are
 parked in the landing zone, the actuator is latched and some of the
 drive electronics are powered down.


 Sleep mode
 ----------
 The spindle is stopped, the heads are parked in the landing zone, the
 actuator is latched and the interface and some of the drive
 electronics are powered down. The drive exits sleep mode when the
 computer issues a hard or soft reset. The drive returns to Standby
 mode when the computer issues a soft reset.


 Shock and vibration
 -------------------
 Shock and vibration may be applied in the X, Y or Z axis. Episodes
 are not repeated more than twice per second.

 The shock and vibration limits specified in this document are
 measured directly on the chassis. If the drive is installed in an
 enclosure to which the shock or vibration is applied, the resonances
 within the enclosure may not subject the drive to movement that
 exceeds the specification limits. The enclosure must be modified to
 ensure the drive movement complies with the specification.


 Handling and static-discharge precautions
 -----------------------------------------
 After you unpack the drive, and before you install it in a system, be
 careful not to damage it through mishandling or static discharge.
 Wool and synthetic clothing, carpet, plastic and styrofoam are
 contributors to static charge buildup. This charge is released when
 you touch another conductor and can damage sensitive components in
 the drive. 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-in-stalled labels contain information needed to service the
 drive. Others are used to seal out dirt and contamination.


 I/O connector
 -------------
 The drive uses a 40-pin, male I/O connector with two rows of twenty
 pins each. The even-numbered pins are closest to the printed circuit
 boards edge. Pin 1 is near the 4-pin power connector. Pin 20 is
 removed for keying purposes.

 We recommend the following part numbers or their equivalents for the
 mating connector.

 Part Description 3M part number
 Connector 40-pin 3M-3417-7000
 Connector 40-pin 3M-3448-2040
 Flat cable AWG28 (stranded) 3M-3365-40

 To ensure the integrity of your data, use a 40-connector, nonshielded
 I/O cable with a maximum length of 18 inches (0.46 meters).


 Mounting the drive
 ------------------
 Mount the drive securely in the computer using either the bottom or
 side mounting holes as described below. Position the drive so that
 you do not strain or crimp the cables.

 Bottom mounting holes. Insert 6-32 UNC-2A mounting screws in the four
 available bottom mounting holes. Do not insert the screws more than
 0.20 inches (6 turns) into the drive frame.

 Side mounting holes. Insert 6-32 UNC-2A mounting screws in any two of
 the side mounting holes on each side of the drive. Do not insert the
 screws more than 0.20 inches (6 turns) into the drive frame.

 Caution. To avoid damaging the drive:
 Use mounting screws of the correct size and length.
 Gently tighten the mounting screws do not apply more than 6
 inch-pounds of torque.

SEAGATE  ST31640A/32140A  PRODUCT MANUAL 36314-101 REV. A  10/95

 Introduction
 ------------
 This manual describes the functional, mechanical and interface
 specifications for the Medalist 1640 and 2140 hard disc drives. The
 drives are referred to throughout this manual by their model numbers,
 ST31640A for the Medalist 1640 and ST32140A for the Medalist 2140.

 The Seagate ST31640A and ST32140A are high-capacity, Fast ATA-2
 performance drives. The drives features include: 3 and 4
 data-surfaces respectively, 5,376RPM spindle speed, embedded servo
 technology, a 16-bit internal microprocessor and an intelligent
 controller.

 These features and others combine to give you high-performance,
 high-capacity and energy-efficient drives. Fast ATA-2 offers you the
 twin-performance advantage of larger data-volume transferred
 at higher speeds. Fast ATA-2 assures you that PIO mode 4 and
 multiword DMA mode 2 for burst transfer rates of up to 16.6 Mbytes
 per second. (The drives support all PIO and all multiword DMA
 transfer modes. The transfer rate for any given operation depends
 upon capability of the entire system.) Fast ATA-2 also means that
 Multiple block read/write is supported. This feature allows multiple
 blocks of data to be stored in cache and transferred in a single
 burst.

 These features make the drives responsive to the demands of
 high-performance Pen-tium and PowerPC-class microprocessors and VL
 and PCI Local Bus architectures.

 These 5,400RPM class drives use embedded servo technology to ensure
 quick and accurate access to information on the drive without thermal
 recalibration interruptions. They use a 16-bit internal microproc-
 essor that is more responsive to 32-bit operating systems and an
 intelligent controller that provides data streaming direct data
 transfers between the host and the drive without microprocessor
 intervention. These features increase the sustained data-transfer
 rate, facilitating video playback and other multimedia operations.
 Coupled with the 1.62-Gbytes and 2.11-Gbyte capacities, the drives
 have more than enough capacity to download and play back a complete
 CD-ROM.

 The ST31640A and ST32140A are energy-efficient drives. They feature
 the power modes defined in the ATA-2 standard. Standby and Sleep
 modes reduce power consumption to a low 0.755 watts (typical). The
 drives enter power-saving modes at the request of the computer and
 can be programmed to automatically enter Idle or Standby modes.


 Formatted capacity
 ------------------
 Medalist drives are low-level formatted at the factory. You cannot
 low-level format them.

 You can operate the drive using many different address
 configurations, provided the number of sectors per track does not
 exceed 63.

 Seek time is the interval between the time the actuator begins to
 move and the time the head is over the target track. Seek time is a
 true statistical average of at least 10,000 measurements of seek
 time. All measure-ments for maximum values are taken under nominal
 conditions of temperature and voltage with the drive mounted
 horizontally.

 Track-to-track seek time is the average of all possible single-track
 seeks in both directions.

 Average seek time is measured by executing seeks in both directions
 between random cylinders.

 Full-stroke seek time is half the time needed to seek from track 0
 to the maximum track and back to track 0.

 Note.Host overhead varies between systems and cannot be specified.
 Drive internal overhead is measured by issuing a no-motion seek.
 Overhead is typically less than 1.0 msec.


 Start and stop times
 --------------------
 The drive is ready within 8 seconds after the power is applied. The
 drive spindle stops rotating within 7 seconds typical after the power
 is removed.


 ATA interface
 -------------
 The drives use an ATA-2 interface. The interface is in compliance
 with ANSI ATA (AT Attachment) Interface X3T9.2/143 Rev. 4.0; SFF
 8011: ATA Timing Extension for Local Bus Attachments, Rev. 2.0 and
 SFF 8019: Identify Drive Data for Drives Under 8 GB.
