Apple has ruined my day. Just spent all of it trying to sync my ipod after restoring it. 3 times now it has synced 8,000+ of 11,000 songs and then decided that it's too corrupt and wipes the cocksucker again completely. Off to work.
it doing that is a sign that there's so many bad sectors on the hard drive that there is no more spare memory to write to. this isn't apple's fault btw - it's just the nature of flash memory.
