WD1003-RA2
Software Installation
The format instructions that you follow are simple procedures to tell
the computer that you have either one or two Winchester disk drives
installed and prepares your operating system to recognize the Western
Digital controller.
You will need to know the parameters of your hard disk drives. As a
convenience to you, we have included a list of the most common hard
disk drives and their parameters. To access this list, return to the
STORAGE CONTROLLER. If your drive is not listed, contact your drive
manufacturer or consult your drive manual to determine drive type and
parameters.
TRANSLATION/NON-TRANSLATION
The motherboard BIOS in most older IBM PC AT's or AT compatible
systems do not recognize the 26 sector per track feature of RLL type
drives. If your hard disk drive has 4 heads and fewer than 663
cylinders, you should select the translation mode controller card and
install software using the instructions provided under the Software
Instructions for Translation Mode. If your drive has greater than
663 cylinders, you will need to use the Software Instructions for Non-
Translation Mode.
NOTE
Translation is only available with F001 controllers. F000 controllers
operate in non-translation mode only. F001's translation program
converts the drive's 26 physical sectors per track to 17 sectors per
track. 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, application program, or system BIOS that
requires a 17 sector per track disk drive.
To format your hard disk drive, you may use 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
DOSprograms, FORMAT and FDISK, after performing the low level format,
regardless of controller configuration.

THE FOLLOWING LOW-LEVEL FORMAT PROCEDURE
WILL DESTROY ALL DATA ON YOUR HARD DRIVE
BACK-UP THE DATA ON YOUR DRIVE BEFORE
CONTINUING WITH LOW LEVEL FORMAT ROUTINE
NOTE
Formatting hard disk drives with the non-translation 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.
CAUTION
Avoid system damage by consulting your
Technical Reference manual to ensure that your
drive type is supported by your host BIOS drive
tables. Not all AT-compatibles share the same
drive tables as IBM.
1. Insert your system Advanced Diagnostic Diskette (or equivalent).
2. Turn on power.
3. Boot diagnostic and select Setup option. After defining drive
types, run System Checkout. Enter 0 after the "Select the action
desired" prompt.
4. Select fixed disk option 17.
5. Select the Format Menu from the Fixed Disk Diagnostic Menu.
6. Unconditionally format the drive with the Format Selection Menu.
7. Enter bad block in the Defect Entry table.
8. Formatting begins. After formatting the drive, press "Enter".
Boot and operate the system normally.
If you require further information or other technical support, please
contact your authorized dealer.

CAUTION
Avoid system damage by consulting your
Technical Reference manual to ensure that your
drive type is supported by your host BIOS drive
tables. Not all AT-compatibles share the same

1. Insert your system diagnostic diskette (or equivalent in drive
A.
2. Turn on the system power.
3. Boot diagnostic and select Setup option.
4. Set up the system for the proper configuration of diskette and
fixed drives (drive type 3 for IBM), basze memory size, expansion
memory size, and display.
5. After performing Setup, execute a low level format using the
Advanced Diagnostics Diskette. Follow the menu and reference manual
instructions.
6. Load and execute the FDISK and FORMAT programs. Follow the menu
and reference manual instructions.
Troubleshooting
Problem: 1790 Disk 0 Error.
Cause: No low level format on hard disk. Wrong drive type
selected. Not enough drive power. Bad cables. Improper
drive selection or termination.
Problem: Drive does not partition.
Cause: Check drive types. Note that drive types for the AT
and AT-compatibles differ.
Problem: "Error Reading Fixed Disk" appears when booting from
hard drive.
Cause: DOS partition not active.
Problem: Winchester activity LED continuously lit.
Cause: No problem. Drive LED selected for latched mode.
Problem: For systems with two drives, both Winchester activity
LEDs light at the same time.
Cause: Improper drive selection or termination. Inspect the
drive cables. If the data cables are straight, then set
drive C's drive select switches for drive select 1 and
drive D's drive select switches for drive select 2. If
the data cables have a twist, set both drives' select
switches for drive select 2. Consult your drive manuals
or dealer for drive switch settings. Finally, under no
circumstances, use twisted floppy cables for the
Winchester drive. Floppy and Winchyester drive interface
connections differ significantly.
Problem: Slow and inefficient operation.
Cause: The biggest culprit for this problem is an incorrect
interleave factor. Therefore, some experimentation with
the interleave factor may be necessary. (Refer to the
format instructions for setting interleave factor).
Interleave factors are very dependent on the host
operating system and application.
Problem: Not getting full capacity from drive.
Cause: You may have an MFM type drive. Consult your drive
manual. The WD1003-RAH is designed for use with RLL
type drives only. DO NOT USE WITH MFM DRIVES.
Problem: Controller does not format a Seagate ST225 to 30 megabyte.
Cause: The ST225 is a 20 megabyte MFM drive. The ST238 is a 30
megabyte RLL drive. This is a good time to point out the
differences between RLL and Modified Frequency Modulation
(MFM) disk drives and controllers. First, RLL equipment
is able to record 50% more data on the drive. Second, RLL
drives must be physically formatted with 26 sectors
because of the greater data density. DO NOT UNDER ANY
CIRCUMSTANCES CONNECT A RLL CONTROLLER TO AN MFM DRIVE.
RLL controllers physically format any attached drive into
26 sectors. Therefore, the RLL controller squishes 26
sectors onto a drive designed for 17 sectors. Squishing
the RLL data onto a MFM drive results in corrupted data.
Finally, the chip sets on RLL and MFM controllers
significantly differ as a result of the first and second
points.
