I recently posted a question about formatting 3.5-inch floppies at 720K
on an XT clone.  From the responses so far, I can see that I didn't
make the question as clear as I could have.  Here's another try,
hopefully better.

A friend of mine has a Toshiba 3.5-inch floppy drive installed on his
XT clone.  Using DRIVER.SYS, he is able to read and write disks on this
drive with both MS-DOS 3.2 and PC-DOS 3.3.  He can also format disks as
360K in this drive.

However, attempts to format at 720K fail in the following manner:  The
drive steps through its full range in 41 tracks and begins to bang.
(ASCII is insufficient for reproducing the noise as he repeated it to
me! :-)  He assumes that this banging would continue for the remainder
of the 80 tracks a 720K disk would have, though he aborted the format
before this would have completed.

He also tried the MS-DOS 3.2 DRIVPARM command with equal success.

Any ideas?  Thanks in advance.
