Technical information

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 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, see Mac OS Guide,
available in the Guide (h) menu. For instructions on reinitializing a hard disk, see “Initializing a
Hard Disk,” next.
If reinitialization 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 your system software
CD-ROM disc with you to the service provider.
