Second request for help.  Nobody responded to the first one...

Please help me!    Recently I installed an EDSI drive into my
true blue PC/AT.  The drive works normal unless I am doing 
extensive disk I/O.  The disk I/O ranges from compiling, using
MASM or MSC5.0, or editing a very large document using Word
Perfect 5.0.

The problem is that very randomly I am getting the dreaded 
"Not Ready reading Drive C:  Abort, Retry, Ignore" error, or
"Abort, Retry, Ignore error reading Drive C:"

  Sometimes pressing retry will succeed, other times, I lose
my work!  :-(  Has anybody else experienced these problems
with the EDSI drives? I have no TSR's running, and I certainly
don't think Word Perfect is trying to do anything tricky with
the drive/controller.

I have the following:
   IBM PC/AT 6 MHz True Blue
   640K RAM - 120nSec
   DOS 3.3 (Also True Blue)
   Western Digital EDSI Controller WD1007/WAH
   Control Data 90 Meg Drive   Model: 94216-106 (ESDI)
                               1:1 Interleave
                               2:1 Also Tried!
config.sys:
   break=on
   buffers=20
   files=20
   device=c:\dos\ansi.sys
autoexec.bat:
   prompt $p$g
   path c:\;c:\dos

The distributor of controller/disk have not been very helpful
so I am turning my "pleas" to the net.

Please send email to:   att!ihlpb!santol
