On Saturday, I added two CDs to my iTunes library, and I synced my iPad over wifi. Now those are the only two CDs on my iPad (all videos are gone too). When I doc and re-sync, iTunes says I have 4000+ songs on my iPad (and shows 40GB of audio in the memory bar), so it's not willing to add back any of the music (or videos) that disappeared. Neither a restart nor a hard reset made any difference. Anything I can do short of a restore? From poking around in the thread, it sounds like my problem is sort of common, but I haven't seen any proposed fixes.
