my i pod is formated for mac and i also have a windows pc so what i was going to do was use music rescue to take the music/videos off it then format it for windows so at 1 point doing it froze and i tryed to force quit but it did not work so i just restarted the mac and when it turned on itunes says itunes could not read the contents of my ipod and i need to restore it. but when i want to play the songs it works fine. so how do i fix it to work normal on the mac?
