So I installed Lion less then 10 days ago. Now my main boot drive won't boot anymore - I'm running on a Firewire 800 backup presently. Disk utility claims it can't repair the disk and I should mount it and back up my data prior to reformatting to rebuild the OS. Problem: disk utility also won't mount the drive. My backup is less than a week old but I just saved some items to that boot drive this morning that I can't get to. Anyone know of any software that will perform an emergency mount of a drive? Not shaping up to be a great weekend for me - fighting a head cold and now this. Oof.
