DESCRIPTION
Standard factory setting. Status read is latched. Used for IBM Personal Computer AT
if Winchester activity LED is connected to J6.
Status read is not latched. Activity LED turns on during drive access. W5 must be
jumpered 2 to 3. Used for Compaq hosts.
Standard factory setting. Selects primary addresses, 1F0 through 1F7 and 3F0 through
3F7 hex. Do not modify the primary address jumper unless your BIOS operating
system is configured to accept more than two hard disk drives.
Selects secondary addresses, 170 through 177 and 370 through 377 hex.
Applicable to the WD1003-RAH. Eliminated by design and artwork changes to the
WD1003S-RAH.
1-2 Standard factory setting. No translation for drive 0.
2-3 Enables translation for drive 0. Translation is only available for 615 cylinders and four
headed drives. In translation mode, the controller translates the 26 physical sectors per
track into 17 sectors. The extra sectors are "translated" into logical heads. To use the
translation mode, select through the Setup program a 615 cylinder and six head drive
type. (This is drive type three for IBM Personal Computer AT users. Not all AT-
compatible systems use the same drive tables as IBM.) This configuration must be
used when running an operating system or application program which requires a 17
sector per track disk drive.
2-3 Standard factory setting. WG and drive select lines only enabled when drive is
accessed. This configuration also provides power up and down protection.
1-2 WG and drive select lines are disabled during power up reset and when + 5V power
supply drops below approximately +4.1 5V.
1-2 Standard factory setting. No translation for drive 1.
2-3 Enables translation for drive 1. Translation is only available for 615 cylinders and four
headed drives. In translation mode, the controller translates the 26 physical sectors per
track into 17 sectors. The extra sectors are "translated" into logical heads. To use the
translation mode, select through the Setup program a 615 cylinder and six head drive
type. (This is drive type three for IBM Personal Computer AT users. Not all AT-
compatible systems use the same drive tables as IBM.) This configuration must be
used when running an operating system or application program which requires a 17
sector per track disk drive.
1-2 Standard factory setting. Controller operates with daisy-chained drive(s). Both can be
3-4 daisy-chained from J1 or drive 0 can be connected to J1 and drive 1 can be connected
to J5. For daisy-chained operation, set the drive select jumpers on the first drive for
drive 0 and on the second drive for drive 1.
1-3 Controller operates with parallel connected drives. Attach drive 1 control connector to
J1.
2-4 Attach drive 0 control connector to J5. For parallel operation, set the drive select
jumpers on both drives for drive 0.
1-2 Standard factory configuration. Ties input high.
2-3 Enables seek to landing zone (cylinder 663) on any seek to a cylinder greater than
615. Used only for 615 cylinder drives. This jumper also changes step rate 0 (24 µsec)
to step rate 15 (11 µsec).

Software Installation Instructions
This section contains instructions for preparing (low level format) the drive to be recognized by
the operating system. Formatting the drive uses one of several software programs, the Advanced
Diagnostics (or equivalent in AT compatibles), Disk Manager from Ontrack Computer Systems,
or Speedstor 4.02 from Storage Dimensions. Use of the programs depends on the controller
configuration. Configuring the controller to use the translation feature requires running the
Advanced Diagnostics program, Setup. Setup defines the drive type for the system and low level
formats the drive. Without translation, Advanced Diagnostics can low level format the drive if
the system BIOS recognizes the 26 sector RLL format. (Storage Dimensions' Speedstor 286
BIOS is a replacement set of BIOS ROMs for the AT system board.) Run the DOS programs,
FORMAT and FDISK, after performing the low level format, regardless of the controller
configuration.
Software Installation Instructions for Non-Translation Mode
NOTE
Formatting disk media with this operational mode requires a host system with a 26 sector
BIOS. If the system does not contain a 26 sector BIOS, Ontrack and Storage Dimensions
produce programs to support the 26 sector RLL drives. For further information on these
programs, contact:

The Disk Manager and Speedstor products are the only products that have been tested by
Western Digital at this publication date. Both work well, providing full usage of the RLL
capacities. However, these are not the only alternatives for removing system limitations.
Contact your dealer for further information.
1. Boot the system with the Advanced Diagnostics. Define the drive type(s)
through the Setup option. After defining the drive types, run System
Checkout. Enter 0 after the "Select the action desired" prompt.
2. Select fixed disk option 17.
3. Select the Format Menu from the Fixed Disk Diagnostic Menu.
4. Unconditionally format the drive with the Format Selection Menu.
5. Enter bad block in the Defect Entry table.
