I started up my macbook pro one day to find that i landed on a screen like this: http://code2care.org/pages/mac-os-x...olor Screen with Spinner and Progress Bar.jpg after 20 minutes or so progress gets to the end of the bar and the computer shuts down. Tried several times with same result. So... I popped in a new HD loaded a fresh install of mavericks and attempted to mount my orig HD(with the problem) via external HD enclosure... It did mount once, but I didn't realize that it wasn't going to mount again so i didn't back up my files at that time (i really wish I did). Disk Utility won't mount it either and trying to repair gives me "Error: Disk Utility cant repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files." At this point I would love to, but... I can not mount the drive!!! DiskWarrior says "Directory cannot be rebuilt due to disk hardware failure (-36,2747)" What can I do?
