How to test a hard disk
You can test an Apple SCSI hard disk with the Drive Setupprogram, which is
on the floppy disk labeledDisk Tools that came with your computer. If your
computer has a built-in CD-ROM drive, and you didn’t receive floppy disks,
you can find the Drive Setup program on the CD-ROM disc that contains
system s o ftware.

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.
