Over the last few weeks I've been getting this message popping up when I plug my iPod Classic into iTunes. The simple fix was to eject it, reconnect it and it'd work. I got fed up with the message so I restored it and it seemed OK for a while but then yesterday I couldn't get it to accept the iPod at all, I just kept getting this same message.
So I restored it again. Today I've just plugged it back into my Mac and I'm getting the same message. The iPod itself seems to be working perfectly apart from this. Of course, it's a fairly major problem in that I can't sync it.
Is a trip to an Apple store the best bet or is there anything else I can do first?
