How to test a hard disk

You can test an Apple SCSI hard disk with the Drive Setup program, which is on the floppy disk labeled Disk Tools that came with your computer. If your computer has a built-in CD-ROM player, and you didn’t receive floppy disks, you can find the Drive Setup program on the CD-ROM disc that contains system software.

1Start up your computer from the Disk Tools disk or the CD-ROM disc that contains system software.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy Disk” in the section “Initializing a Hard Disk” earlier in this chapter.

2Open the Drive Setup icon.

You may need to look in a folder called Utilities to find Drive Setup.
