Somewhat. My girlfriends 5g 80gig iPod took a dump and according to iTunes it had NEGATIVE 170 gigs available. We tried to restore it using iTunes for Windows and it said it was restoring for over 12 hours......Tried it again, same thing. Decided to take it to my house and hook it up to my MBP, got it restored in about 30 seconds. Plugged it into my PC, reformatted it back to a Windows and it's good as new.
