I have had this problem since I bought the darn thing in 2006 or 2007--most of the time I plug my iPod in, the computer fails to recognize it. I usually need to both restart my computer and do a hard reset of the iPod itself. This problem has persisted through several computers, both Macs and PCs. In retrospect, I should have taken it back to Apple in year 1, but I didn't. Has anyone run into this issue? Do you think a total restore might help? (This option is never mentioned in the help section for this issue, so I have been reluctant to try it.) It otherwise works ok and the 80gb is sufficient for my needs, but the 15 minute sync process means I never sync and end up frequently not having the music I want to on it.
