Is it possible to do a restore if your PC and Mac cannot detect the ipod? My ipod is formatted for windows. I've had it for 1.5 years, it's a 4g 20gb version. Just last week it was screwing up on me. About 75% of the time when I hit Fast Forward it would take forever to load the next song, sometimes it would just skip to the next track that it could read. I noticed this happened when plugged into a car charger and a when used a few hours after unplugging from car charger. Well, now it seems to have crapped out on me. It's trying to boot up and will show the apple logo for awhile then start over again...every once in awhile you'll see the folder and the ! icon.
