Well, perhaps the device isn't consistently writing data to the correct locations.

Pete is quite as competent at solving this kind of problem as I am. And he knows the ub driver much better, so I'm happy to bow out and let him worry about it! :-)
Just out of curiosity, if you plug the player into a Windows system without installing any special drivers first, will Windows be able to read and write files okay? If it can, a USB packet trace may give Pete a clue as to where to look.
