How do I know if my disk is recoverable. My macpro crashed. I do have a backup on the time capsule which is accessible. When I start the process the system is stuck on select a destination. Is my hard disk messed up?
If Lion or Mountain Lion try booting into OS X Recovery (press command-r at startup) and running Disk Utility, Repair Disk.
Sounds like it.
My computer is not working, is my personal data lost?
