This section describes how to determine if the 610CT 3.5-inch external floppy disk drive is
functioning properly.  If the 3.5-inch external FDD is not connected to the computer, connect
it and perform the steps below starting with Procedure 1 and continuing with the other proce-
dures as required.

Procedure 1:

FDD Head Cleaning Check

Procedure 2:

Diagnostic Test Program Check

Procedure 3:

Connector Check and Replacement Check

FDD head cleaning is one option available in the Diagnostic Program.  Detailed operation is
given in chapter 3, Tests and Diagnostics.

After loading Toshiba MS-DOS, run the Diagnostic Program and then clean the FDD heads
using the cleaning kit.  If the FDD still does not function properly after cleaning, go to Proce-
dure 2.

If the test program cannot be executed on the 610CT, go to Procedure 3.
