Subtests
The five subtests in the Hard-Disk Drives (Non-SCSI) test group confirm the following drive functions:
Disk Controller Test
Checks the internal microcode of the hard-disk drive controller
Forced Error-Correction-Code Test
Checks the ability of the hard-disk drive to identify and correct errors
Seek Test
Checks the drive's ability to search for a specified track on the drive and to position the read/write
heads of the drive to all tracks

be read correctly
Write Test
Positions the read/write heads at each cylinder of the drive and verifies that all tracks on the drive can
be written to correctly
IDE CD-ROM Drives Test Group
The subtests in the IDE CD-ROM Drives test group check the functionality of the integrated drive electronics
(IDE) CD-ROM drive. Before conducting an IDE CD-ROM test, insert a CD with audio and data tracks (such
as a multimedia CD) into the drive.
NOTE: The Audio Output Test requires a CD with audio tracks; all other subtests in this test group
require a CD with data tracks. If the CD-ROM drive contains a CD that does not have the required
data or audio tracks, the subtest fails.
