[comp.sys.ibm.pc.hardware] WD 27X RLL Controller help

I have an odd problem, maybe someone can help?

1) I had an XT, a ST-157R-1 hard drive, and a WD 27X (RLL) controller
   running just fine, drive divided via OnTrack --> 3 partitions.

2) I upgraded to a 286-12 board, using same HD & controller.  Worked fine
   for one day.  I let SpinRite run overnight to adjust interleave, etc.

3) The next time I booted the computer, it acted as if there was no drive
   C:, not to mention logical drives D: or E:.

4) I guess I should get a 16-bit controller.  More importantly though,
   can I 'reset' or program the controller so that it WORKS (whether it
   is the 8- or 16-bit doesn't matter) w/o doing a LLF, so I can salvage
   some of the data?  (I only had about 15 megs worth... but still...).
   i.e. does anyone know where the drive info table is in the controller /
   how I can correct?

Thanks very much for any help!  I will post summary if interest abounds.
