This section describes how to determine if the FDD is functioning properly. Perform the steps
below starting with Procedure 1 and continuing as required. Figure 6-4 gives an outline of the
process.
Procedure 1: FDD head cleaning check
Procedure 2: Diagnostic check
Procedure 3: Connector check and replacement check
Procedure 1
FDD head cleaning check
The FDD heads can become dirty over time, affecting their performance. Use an FDD
cleaning kit to clean the heads. If the FDD still does not function properly after cleaning, go to
Procedure 2.
Procedure 2
Diagnostic check
Insert the Diagnostics Disk in the FDD, turn on the computer and run the test.
If no FDD problem is detected by the diagnostic test, the FDD is functioning normally. If an
error occurs, go to Procedure 3.
Procedure 3
Connector check and replacement check
The 3.5-inch FDD is connected to the system board. For instructions on how to disassemble
the computer and then perform the following checks:
Check 1 Make sure the FDD flexible cable is firmly connected to the FDD and system
board. If any of the connections are loose, reconnect firmly and repeat
Procedure 2. If any of the connections is damaged, or there is still an error, go to
Check 2.
Check 2 The FDD unit or FDD flexible cable may be defective or damaged. If the FDD is
still not functioning properly, perform Check 3.
Check 3 Replace the system board.
