a friend of mine has a powermac 533 G4, OS 9 will not boot, but OS X will. When running the disk utility verification it reports the "keys are out of order" and disk utility cannot repair the problem. We then entered single user mode and used fsck -y to try and repair the disk to no avail. What can we do next to repair the disk? Are there any shareware type utilities that could work? Any help is greatly appreciated.
