Apple Power Macintosh (7100 Series) - Manual (Page 99)

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 program. Some disk repair programs
let you recover information from a damaged disk.
m Consult a computer repair specialist for help.
m Once you have recovered all the information you can, erase (reinitialize)
the 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).
