I've been trying to find a solution to this online but can only get to people with the same problem, no further. Basically I moved my iTunes onto an external hard drive to free up space on my laptop. All good, except now EVERY time i try and update my iPod it says it's corrupted and needs restoring. The best advice ive heard is to move the iTunes files back to their original location, but this defeats the point and would just be undoing what I've done and set out to do.
If anyone can help I would love you forever, unconditionally.
