I keep getting an error message when trying to restore my iPod
I have a problem with my iPod 30GB Classic of showing no music, however when I connect it to my PC, the iPod shows up in Windows as being filled with files. The other problem was that iTunes would freeze up when my iPod was connected.
You ought to get into the factory check screen & do a diagnostic on the hard drive.
To do that is similar to the reset screen- except you hold the centre button/back.
In the menu that shows up, use the forward button to select IO/HDD and see if the drive passes.
You can run all tests, as well.
