I assume that your new primary drive is empty (except for the OS and player software), right? If not, if it's got song files on it, then you've probably got conflicting FIDs between drive0 and drive1 and that's your problem.

If it is empty, and it's got the space, then I'd suggest copying all the FIDs to drive0 and wiping them off of drive1. Then it all should work

No need to copy the fids to drive0 -- you can safely leave them on drive1 -- but do make sure there aren't any conflicts and killing any new ones on drive0 while 'importing' a consistent set using a new drive seems a safe way ensuring this. When there are no fids on drive0, rebuilding the database happily recovers all songs and playlistinfo on drive1; thereafter new songs are allocated to the drive with the most space.

I used this method to move all my somgs from the Mk1 to Mk2 -- it worked without a hitch
