[QUOTE="bobtomay, post: 905522, member: 24160"] Most of what you've read online was written before Time Machine more than likely. If you have a current Time Machine backup then you're good as far as your data goes. First I'd try booting from your OS X dvd - Utilities on the menu and Disk Utility. Try a Repair Disk from there. I have not had a drive get to this point since I began using OS X, but from what I read it may or may not fix it. Next option for me is either Disk Warrior / TechTool Pro - seems to be DW is recommended more often. You'll need the CD. It may or may not fix it. Or, just get a new drive. It's possible you'll get DW and still need a new drive. If either of these do repair the drive, see if you can now boot into the OS. If not, I'd suggest back to Disk Utility and erase and re-format. To install you'll also boot to the OS X dvd and go to Utilities, then select 'Restore System from backup' - [URL="http://docs.info.apple.com/article.html?path=Mac/10.5/en/15638.html"]here is a guide[/URL]. This could also be a sign of a failing drive. Personally, I have never trusted a drive that has gotten to this point of failure for my day to day work again, whether it could be repaired or not. The ones that could be repaired I've have moved to secondary storage only. I do have one 40GB drive bought the week they came out that failed similarly about 6 years ago and is still running as a storage drive. For the most part though, I toss 'em. [/QUOTE]
