 Install master/slave jumpers
 ----------------------------
 In a two-drive system, you need to designate one drive as the master,
 or drive 0, and the other drive as the slave, or drive 1. In a one-
 drive system, configure the drive as a master (no jumpers installed).

 Alternatively, you can configure the drive as a master or slave
 using the cable select option. To use this option, the host system
 and both drives must support cable select. Cable selection 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 configure an ST9655 family drive for cable select, install both
 master/slave jumpers.

 Notes On Installation
 =====================

 Mounting the drive
 ------------------
 Mount the drive securely in the computer using M3X0.5 metric screws
 in the four bottom mounting holes or the four side mounting holes.
 You can mount the drive in any orientation. Be careful not to strain
 or crimp the interface/power cable.

 Caution
 To prevent damage to the drive:

 - Be careful not to bend the drive connector pins, especially when
   plugging the drive into a fixed connector.

 - Use mounting screws of the correct size and length.

 - Gently tighten the mounting screws_do not apply more than 3
   inch-pounds of torque.

 - Do not insert mounting screws more than 0.15 inch.

 NOTE
 This drive meets industry-standard MCC mounting specifications. When
 installing this drive in a fixed-mounting application, you must use
 MCC-compatible connectors and mounting hardware. If the mounting
 holes in your computer do not line up with the mounting holes on the
 drive, your computer may not be MCC-compatible.


 Attaching cables
 ----------------
 This drive is designed for a host computer that supplies interface
 signals and +5V power through a single 44-pin connector and cable.

 Configuring your computer
 -------------------------
 Before your computer can recognize a new drive, you must enter basic
 information about the drive into the computer's longterm memory
 (usually a battery-powered CMOS chip). The computer's basic input/
 output system (BIOS) uses this information to control the flow of
 data to and from the drive.

 NOTE
 Some newer computers can automatically determine your drive type and
 configure themselves appropriately at startup. Read your system
 manual to determine whether this applies to your computer.

 If your computer cannot automatically determine your drive type, you
 must run a system setup program to specify the number of cylinders,
 heads and sectors for each drive in your system. The table below
 lists cylinder, head and sector information for the ST9655 family
 drives.

   +-----------------------+----------+----------+----------+
   |Drive specification    |ST9655AG  |ST9550AG  |ST9385AG  |

   +-----------------------+----------+----------+----------+


 Formatting and Partitioning the drive
 -------------------------------------
 CAUTION
 Formatting or partitioning a drive that contains data destroys that
 data. Make sure all data has been safely backed up before re-
 partitioning or reformatting a drive that contains data. Seagate
 Technology assumes no liability for lost data.


 Low-level formatting
 --------------------
 Seagate ATA Interface drives are low-level formatted at the factory
 and do not require additional low-level formatting before use.

 NOTE
 If you are installing only a single drive in your computer, you can
 use the DOS program SETUP.EXE (supplied with DOS 5.0 and above) to
 partition and format the drive. See your DOS manual for details.
 After you successfully run SETUP.EXE, your drive will be ready to
 use, and you can skip the partitioning and formatting steps below.


 Partitioning
 ------------
 The partitioning process subdivides a single disc drive into
 partitions that behave as separate logical drives (labeled C, D, E,
 etc.). You can also set up the entire disc as a single partition.

 1. Restart your computer. Boot up the computer using a diskette that
    contains DOS system files.

 2. Run the FDISK program. Insert a DOS program diskette containing
    the FDISK program into your diskette drive. At the DOS prompt,
    type fdisk and press ENTER. Then follow the directions on the
    screen to create one or more partitions. See your DOS manual for
    details. If you are partitioning a drive that will be used to
    boot the computer, make sure that the primary partition is marked
    active.


 High-level formatting
 ---------------------
 High-level formatting verifies the information written by the low-
 level format and creates file allocation tables used to catalog and
 access files.

 1. Run the FORMAT program. Insert a DOS program diskette containing
    the FORMAT program into your diskette drive. At the DOS prompt,
    type format, followed by the drive letter for the first drive
    partition you want to format (for example, format C:). Then,
    press enter. Repeat this procedure to format each of the new
    drive partitions you have created. Consult your DOS manual for
    FORMAT command options.

 NOTE
 If you are formatting the drive partition that will be used to boot
 your computer (the "C" drive), copy the DOS system files to this
 drive. To do this, type /s after the format command (for example,
 format C: /s).

 2. Verify the drive capacity. After high-level formatting a drive,
    you can verify the usable drive capacity by running the DOS
    CHKDSK utility program.


 Compatibility Notes
 -------------------
 The ST9655 family drives conform to the ATA interface specifications.
 The host system BIOS must provide support for the ATA interface
 command set. For a detailed description of the ATA commands
 implemented by these drives, see the Seagate ST9655 Family Product
 Manual and the Seagate ATA Interface Reference Manual.

 - In accordance with ATA specifications, the system BIOS must reset
   any emulation/translation parameters after a hard reset.

 - In some configurations, a ST9655 family drive may supply up to
   16 bytes of error correction code (ECC) with the Read Long and
   Write Long commands. Depending on the drive type, your system
   BIOS may look for 4 bytes of ECC. If your system BIOS expects 4
   bytes of ECC and the drive supplies a different number of bytes,
   some drive diagnostic programs may fail,typically resulting in
   timeout errors. Consult your computer documentation or call your
   computer dealer or manufacturer for information on configuring
   your computer to receive more than 4 bytes of ECC.

 - Some older drive diagnostic programs may incorrectly report an
   ECC detection failure when analyzing an ST9655 family drive. This
   occurs because the drive hardware corrects the data automatically,
   avoiding the error rather than reporting it. Such a report does
   not indicate a drive malfunction.
