My iMac running OS X10.4 began freezing up when using various apps, very slow on loading web pages, etc. Had to force reboot holding down power button.
Following advice on this Forum, I tried using disk utility (after booting from OS installation disk), but repeatedly unable to repair. Kept getting error message after attempts "The underlying task reported failure on exit". The errors noted in running the app were:
1. Incorrect # of thread records (4, 29561)
2. Invalid volume file count (should be 667,388 instead of 667,199)
3.The volume Mac HD needs to be repaired.
Also ran fsck -y with same results.
I have certain of my files backed up on external USB drive using Super Duper & recently backed up same to one of my PC's internal HD's using Crash Plan.
Since I hopefully can use those sources to restore my data. But what action do I need to take to repair the Mac HD? Reinstall OS ? or ...??
Thanks in advance for any assistance.
