Diskette Drive Test (2625 365X, XD - 2635 380-385)

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.

FDD-1 represents the built-in diskette drive for 365X. FDD-2 represents a diskette drive in the Port Replicator or a diskette drive attached through the external diskette drive connector.

  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:
  1.  Select the advanced diagnostics mode and  select Tool, then  select the FDD-1 or FDD-2 icon and  press the spacebar.  A OK mark appears next to the selected icon.  Insert a blank diskette when instructed.
  2.  Run the diskette drive test.
  3.  If the controller test detects an error, FRU code 10 appears.  Replace the system board.
  4.  If the controller test runs without errors,  the drive read/write tests start automatically.
  5.  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.
