When I take out the original drive and install a different drive (primary) drive, these fids on the secondary don't seem to be recognized.

I don't know what's going on there, but the FAQ only talks about copying the fids to your replacement primary drive. You're talking about using an already-populated secondary drive, something I never tried.

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.
