I picked up a known working MFM drive at a flea market. The paperwork 
that came with the drive said the drive was compatible with MFM or RLL. 
I was suspicious, but tried formating it with an RLL controller anyway.
I now suspect that the drive has two versions, one of each format. The 
drive doesn't work with the RLL controller. I tried to re-format the 
drive with an MFM controller and now the drive doesn't work on MFM 
either. The formatter I am using is the debug callable one on the WD 
controller. Anybody know of a way to get the thing working with the 
MFM controller again?
