If MacCheck detects directory corruption during its file system test,
locate the Disk First Aid program on your Utilities disk (Performa owners)
or Disk Tools disk (Macintosh owners.)
Follow the procedure detailed below:
1) Shut down your Macintosh from the Finder's Special menu.
2) Insert your Utilities or Disk Tools disk and turn on your Macintosh.
3) When the Finder appears, run the Disk First Aid * program. (Note: Be
careful to designate the drive that MacCheck detected the problem
on, as the drive that needs to be fixed.
4) Choose Quit to return to the Finder and choose Restart from the Special
menu to restart your Macintosh.
* Apple recommends Disk First Aid v7.2, found on the Software Utility Update
1.0 disk, available from AppleLink and other online services.
Occasionally, Disk First Aid versions prior to version 7.2 will not
find or fix the problems that MacCheck has detected. If you run MacCheck
after running Disk First Aid, MacCheck may still detect file system
problems. If this occurs or if MacCheck tells you that it detected problems
that Disk First Aid cannot fix, the problems can be corrected by
reinitializing your hard drive using Apple HD SC Setup. Please make sure
that you have backed up your drive (using Apple Backup if you are a
Performa user) before reinitializing your drive.
Some third-party utilities may be able to repair problems that Disk First Aid
cannot repair. However, reinitializing your drive is the only way to be sure
that problems that MacCheck detects are corrected.
