  I have a RLL hard drive which has more than 1024 cylinders. I've heard
  that there is a controller that uses special mapping so that I can 
  map more heads and less cylinders.

  Could anybody tell me which controller can do this mapping ?

  Apparently my controller (OEM version of WD1006-SR2) cannot do
  this mapping function.

  If I mapped those extra cylinders to ghost heads, then will SpinRite or 
  Norton Disk Doctor run flawlessly ?

   Thanks.
