Hello
You may have noticed that your question has been here for a few days, with a low amount of views, and no replies (except for mine)
ComputerHope really isn't big on Macintosh or Apple. We are PC users (most of us) although some of us forum members do use Macintosh's.
If it goes for a few more days, go ahead and post in the Others section where you are sure to get some better help.
Or, if a moderator would like to, it would be nice if this post could be moved.
BTW: Try running a disk check on your iPod.
