NOTHING works... Once I connect my iPod to the PC the device HDD gets crazy... It goes on and off (and with a "click" sound). I cannot see it on my PC as at all (and of course not on iTunes as well). It looks like the HDD is seriously damaged (although the iPod didn't fell or anything like that).
It is a new iPod! Bought it about 3 months ago!
Any other creative ideas?
