Last chance?

So, your iPod still shows sad face and it wasn't software problem..
For those who have iPod with hard drive (like iPod classic or iPod Video), there is one more chance:

1. Open the iPod (likely it wont be pretty and it’ll scratch).
2. Locate the hard drive.
3. Reset the hard drive connector (fancy way of saying: take it off, then put it back).

For those, who have iPod with flash memory card (like iPod nano, shuffle etc.) this way would'nt work, because flash memory card doesn't have connector.
