My Mac Book decided to pull a Humpty Dumpty, and landed on its spine (see below for details). I tried recovering files, but was unsuccessful, as described here: http://forums.macrumors.com/showthread.php?p=14386344#post14386344 So I used the OSX DVD to open Disk Utility and erase the drive. Then I started reinstalling OSX. It took several hours, but seemed to be making progress. Then it went black, made the startup chime, and displayed the Apple logo. Ten minutes later, it did that again. Then it did it again. After the 8th repetition of this, I turned it off. What now? Should I go buy a new HD and install it? Or is there something else to try first? Thanks! Background Info: My MacBook crashed- literally- onto the floor. I picked it up and opened it and it made a lot of bad sounding mechanical noises. I was able to drag windows around and minimize them, but it was very sluggish. When I clicked on an image on the desktop it opened up, but only after several minutes. I restarted, but it just showed a logo and a spinning wheel for an hour. I took it to the Genius Bar, and they said I should try using FireWire Target Mode to save files and then do a full erase of the hard drive, and reinstall everything. I have a Time Machine backup, but it's not recent, and I'd like to save pictures that aren't on it.
