    The only reliable way to do this is to switch-launch to a floppy
disk

    [hold down the pretzel-key and double-click an application on the
    floppy.  the floppy must include a valid system & finder]

and then "eject" the hard-disk by trashing it.  Unfortunately, there's
no way to "re-insert" the hard-disk when you're finished, except by
rebooting (at least, not with my HD).

    Also, although it's not likely, a really nasty program can still
get out the SCSI port and do something.
