UPDATE ...

I found that by disabling the 32-bit fast disk-access method in
Windows 3.1, the problem above "went away".  I guess the controller
is NOT 100% compatible with the 32-bit disk option (yet).  I haven't
really noticed any great performance increase with the option anyway
so that's no big deal to me.

Look for another UPDATE post hopefully this week regarding my initial
problem:  failures of buffer cache flushing after an XCOPY.

               Yes, that IS a '%' (percent sign) in my network address.
