   I recently posted about my misadventures with the Mitsubishi MR535 drive
in RLL mode and the 1024-cylinder limit. I seem to have mostly generated
controversy on whether an odd number of heads is possible...

   So I'm going to ask again: I have a Western Digital WD1002A-27X RLL
controller. This is an 8-bit XT controller running in an XT. I have no docs
for it.
   I have been told that some WD controllers can disable the 26-to-17
sector remapping. Can this one do that? What are the pitfalls of doing so?
Will I be required to run Disk Manager on all my drives?
   Or, can I get a BIOS upgrade which will allow disabling the remapping?
   Or, should I get another controller?
