Diskette Drive Test
.Diskette Drive Test
Do the following to isolate the problem to a
controller, drive, or diskette. A scratch, write enabled,
non-defective 2HD diskette is required.
Make sure that the diskette does not have more than one label
attached to it. Multiple labels can cause damage to the drive
or can cause the drive to fail.
Do the following to select the test device:
- Select the advanced diagnostic mode and
select Tool, then
select the icon FDD-1 or FDD-2 and
press the space key.
A OK mark appears next to the selected icon.
Insert the blank diskette when instructed.
- Run the diskette drive test.
- If the controller test detects an error, FRU code 10 appears.
Replace the system board.
- If the controller test runs without errors,
the drive read/write tests start automatically.
- If the drive test detects an error, FRU code 50 for FDD-1
or 51 for FDD-2 appears.
If the diskette itself is known to be good, replace the drive.
- If the drive is attached through a Port Replicator
as FDD-1 or FDD-2 and the test detects errors,
move the drive to the computer's diskette drive connector directly,
and test it again as FDD-1.
If no errors occur at the FDD-1 position, the drive is not defective.
Go to Port Replicator Checkout in Common Devices
Checkout section to isolate the replicator problem.
- If the drive is attached through an Expansion Unit, go to the
service manual of the Expansion Unit to isolate the problem.
- If the drive is attached through a Diskette Drive Attachment Unit,
replace the unit.
