Music issues
I reset my iPod touch, and now every time I go to sync it with my library, it appears full. It claims that my iPod does not have enough GB, however it was just fine before I reset it. Any solutions?
Without knowing what you did since there are many "resets",
Verify your sync setting since it sounds like you are trying to sync more media than you think/that storage available on the iPod
iTunes: Syncing media content to iOS devices and iPod
Try syncing using the manual method
