<Sorry, Mr. Video -- this is how you do it:

As the question stood, I was not in error.  Normal MS/PC-DOS does not allow
you to do it.  The 360K drives don't have a signal that can be checked by
the system.  There is always a utility out there that someone will come up
with that will do the trick.  I suspect that this little utility exercises
the drive so that it can capture the BIOS response and do an ERRORLEVEL.
