I removed everything from the problem player by doing a disk builder on it (both drive0 & drive1), then FTP'd the entire contents of drive0/fids & drive1/fids from my "Good" player onto it. Shouldn't that make them identical?

Hang on, did you do this before or after the fsck which reported the errors?

It was immediately before that fsck that your filesystem got corrupted. If you haven't blanked and re-copied the bad player since then, it's not surprising that it's still different from the good player.
