Quad-density (720 kbytes / diskette) is not compatible with either
High Density (1.2 Mbytes / diskette) or Double Density (360 kbytes /
diskette).  The AT-compatible High Density drives and controllers are
capable of writing either HD or DD format, but not QD format.  If
you're really using QD media, buy some DD or HD media, and I think
your problems will be solved.
