So I'm having a problem fixing my friend's 120GB iPod Classic. He says the problem started when one day he hit play and it said there are no artists, no music, etc... It now says that there's 54+ gigs of "other" on the disk. I tried mounting it in OS X on my MBP and it actually caused iTunes to completely lock up and couldn't be reopened until the iPod was unmounted, so I couldn't do a software restore. I tried in Windows and essentially the same thing happened. iTunes locked up, for a while it said I should set up the new iPod but that took almost 20 minutes and choosing to restore didn't work at all (weird). I want to wipe it with disk utility in OS X and restore it there and then reformat it in Windows, is that going to screw more stuff up? Should I wipe the entire disk or just the iPod image? Or should I just reformat it in Windows? This is driving me crazy because what should have been a simple restore has taken the better part of the last four hours. Any help is greatly appreciated.
