SYMPTOMS
========

When you attempt to format a floppy disk using an LS-120 floppy disk drive drive
with a third-party ATAPI/IDE miniport driver, you may receive the following
error message on a blue screen:

  An exception 0E has occurred at 0028:C0021E77 in VxD IOS(01) + 00001197. This
  was called from 0028:C00219AF in VxD IOS(01) + 00000CCF.

CAUSE
=====

This problem occurs because the data is being moved in words (16-bit segments)
instead of bytes (8-bit segments).
