After sync, iPod Resets and and says 'No Music'

I recently found out that a corrupt file was jamming up my first gen 160GB Classic. If i played the track, the ipod would start skipping to the next track, but not play any music. If i changed artist or album or anything it would do the same thing. I'd have to reset it, but if i tried that same song, it would do the same thing.

I bought a new ipod, brand new 160, before realizing it was just a corrupt 4-song EP. (i synced the new one, played the same EP and it did it again!) I'v since re encoded the tracks and it works fine now on the new ipod, but while trying to figure out the problem on the old one, i may have killed the ipod.

Now when i sync the old one, it'll reset itself after the sync and than tell me there is no music on it while the ipods status bar in itunes shows it is nearly full. If i click the ipods drop down menu on the left and click on Music, it shows all the songs. If i try to restore it, i get an error (not at home, can't remember what it said) I did try to erase it using Disk Utility, selecting Mac OSX (Journaled) assuming it would just error out but hopefully erase it still. Im starting to think that may have screwed it up although the ipod still has all its menus and everything.
