I have recently degraded my vista machine to xp. Everything was going smoothly until I installed iTunes 10 and tried to copy mp3s file from one folder on a external hard drive to a folder on the desktop. It would copy most of the mp3s except for a handful. These files would then be corrupted and then impossible to get rid of. It would give me the same "i/o device error" message for each of the problem mp3s. Any explanation and solution? Any help would be appreciated.
