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.

Test

Drive speed test

Random R(ead)/VV(rite) test

Sequential R(ead)/W(rite) test

Drive change line test
