- 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 menu. 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 may select jumper settings to enable the translation
- mode of the 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.
-
- 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.

- 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.

- 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 WD1003S-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.
