Thanks anyway Plankton but that was less than useless.
After using their "doctor" program, it was happy to tell me that ALL of the files were "corrupted" to the point where the ipod is no longer recognised as such. Sigh.
Edit: One good thing is that the whole ipod is now seen as empty, so technically, once I can get the thing recognised I can start putting on just the albums I want, so maybe in a weird way it did work.
Thanks anyway.
If this fails then I'm afraid it's itunes once again... dear god no!
