Troubleshooting the Diskette Drive Subsystem

If the monitor displays a system error message indicating a diskette drive problem during execution of either the boot routine or the Dell Diagnostics, the problem may be caused by any of the following conditions:

•The system configuration settings do not match the physical diskette subsystem configuration.

•

The diskette drive cable is not properly connected or is faulty.

An expansion card is interfering with proper drive operations.

A diskette drive may be improperly configured.

The diskette drive is faulty.

The computer's power supply is not providing sufficient power for the drives.

The computer's diskette drive logic is faulty.

Follow these steps to troubleshoot the diskette drive subsystem:

1.Enter the System Setup program, and verify that the system is configured cor- rectly for the Diskette Drive A setting.

See “Using the System Setup Program” in the User's Guide for instructions.

2.If the system configuration settings are incorrect, make the necessary correc- tions in the System Setup program, and then reboot the system.

3.Run the Diskette Drives test group in the Dell Diagnostics to see whether the diskette drive subsystem now works correctly.

See Chapter 5 “Running the Dell Diagnostics,” for more information. Did the tests run successfully?
