The problem is THE  floppy driver.  In day's of yore the BIG
floppies - 8" fellas - had mechanisms that would lock the disk
in the drive if it was in use by the OS.

Current SCSI removeable media do that - things such as the Zip
drives and the Jaz drives - and take an 'eject' or resetting
the SCSI adaptor to free them.

Just a case of making things cheaper.  Some floppy drives don't
notify the system of a medium change - as many DOS users found
out when they scrambled their floppies after changing disks.

Good advice.   Too bad people don't always look at the light
before pushing the button.   Of course this doesn't help a bit
if the drive is not being accessed, and it is still mounted,
and the drive doesn't support disk change logic/circuitry.
