Apple Macintosh 6500 - Manual (Page 160)

If Disk First Aid cannot correct the problem
m Try repairing the disk again. Sometimes repeating the process corrects
the problem.
m Use another disk repair or recovery application. Some disk repair
applications let you recover information from a damaged disk.
m Consult an Apple-authorized service provider for help.
m If you can’t repair the disk, you’ll need to reinitialize it, which erases all
the information on it. Before you reinitialize, be sure you recover all the
information you can and back it up. Then erase (reinitialize) the disk. For
instructions on reinitializing a floppy disk (that is, preparing it for use), see
the “Disks” topic area of Macintosh Guide (or Mac OS Guide), available in
the Guide (h) menu. For instructions on reinitializing a hard disk, see the
next section, “Initializing a Hard Disk.”
If initialization doesn’t work, discard the damaged disk (if it’s a floppy disk)
or take it to your Apple-authorized service provider for repair (if it’s a hard
disk). Bring the CD-ROM disc that contains system software which you
received with your computer, with you to the service provider.
Initializing a hard disk
The hard disk inside your computer was initialized (formatted for use) at the
factory, so you shouldn’t need to initialize it. You need to initialize a hard disk
only if one of the following is true:
m You purchase an uninitialized hard disk from another manufacturer.
m Your hard disk is damaged and can’t be repaired.
If a hard disk needs to be initialized, its icon does not appear on the desktop
when you start up the computer using another disk.
You initialize your internal hard disk using an application called Drive Setup,
which is on the CD-ROM disc that contains system software and came with
your computer.
