The volume Macintosh HD was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
also have done the repair with the start up disc several times.
All you're doing is verifying, not repairing. To repair, you have to boot from your installation disc and launch Disk Utility from the Utilities menu in the menu bar.
Disk Warrior.
Make sure you have two backup sets. TimeMachine plus a clone. Might want or need a recovery drive partition also and Data Rescue 3. An emergency Mac OS 10.6.8 boot volume (30GB) is handy.
- I never use the DVD. Use another boot drive volume instead.
In theory Single User Mode and fsck and follow with Safe Boot can fix some but not those errors.
CCC or SuperDuper (or other) plus Disk Warrior is your best - of course better to have a backup image clone that you can just restore, too.
Yes I have run the repair from the start up disc. EVery few days this message comes up. Just updated itunes and again this message appears.
Then your drive is failing. Replace it and restore from backup. Do not waste your money on Disk Warrior.
thanks so much. am still under warrenty and will set up genius appt.
Warranty: while you wait, go buy a couple drives!
And backup sets.
Then use the replacement drive from Apple (recertified refurbished) as a spare backup.
I should save you the trouble and tell people not to waste their money, except DW can and does work but obviously not on a failed/failing drive.
Do you really feel that bad? Gee, I should tweet that to Facebook fans and others.
DW is a recovery tool, useful only to those who have no backups or inadequate backups of a damaged HFS volume that Disk Utility can't repair. Otherwise it's completely useless.
