My buddy's hard drive got all messed up when he installed snow leopard, so it needs to be wiped clean and reinstalled. I can only boot from the DVD install disk. My question is, how do I back up specific files he wants to save on an external hard drive before I wipe it clean? I tried just backing up the whole drive by using Restore in disk utility, but it wouldn't work. Is there anyway I can navigate the hard drive to copy the files I need onto the external while booting from the install disk? Any other solutions would be greatly appreciated!
