The Diskette format test checks the format capability of the

diskette drive and its controller. In order to run the test, you
need a blank diskette that has been formatted using the

MS-DOS FORMAT command and that is not write-protected.
When the program prompts you to insert a diskette, insert
the newly formatted one.

Once the Diskette format test is completed successfully, you

must use the test diskette to run any of the tests in the

following table. These tests will not run properly unless the
diskette has been previously used for the Diskette format

diagnostic test.
