1. I find it between difficult and impossible to believe that you have a 40Mb
  ESDI drive.  ESDI drives smaller than about 80Mb are very very rare.

2. It a recent microsoft technical seminar, we were presented with the 
  following info, fact or fiction, I don't know for sure...  The 32 bit
  disk swapping enhancement of windows 3.1, will _never_ be compatible
  with existing scsi drives or controllers.  A ESDI driver is being worked
  on, and may be available sometime.  Sometime may or may not = Never.
  ESDI drives have the advantage that as you have more money, and things
  come down in price, faster and faster controllers (cached controllers,
   etc...) can be purchased.

3. IDE drives and controllers, could already be windows 32 bit disk access
   compatible.  IDE drives and controllers are about as fast as they are
  ever going to be, or are capable of being.  However, they do have plenty
  of throughput, and i/o headroom for faster systems, today.  They will
   start showing age, as systems keep doubling in speed, and larger and
  larger software becomes available.  On the other side, the tremendous
  cost of ESDI drives and controllers will be a serious drawback to the
  wide acceptance of these systems.
