Ipod Magic

Well, yet again my Ipod was playing up. This time it was clicking away, failing to play sometimes and failing to sync. Then it began showing the exclamation mark error. I thought it was probably a dead hard drive. Tried the usual restore and formatting it from Linux to no avail. I noticed a few sites recomending I knock it about and give it a slap. So I placed it in one hand and hit it on the back with my other. Nice and hard, and lone behold it worked! Seems to be working just fine now. Crazy.
