How can I prevent someone from ejecting a floppy disk out of a Macintosh?
DISCUSSION ------------------------------------------------------
Some educational users have asked about disabling disk-ejecting procedures
to prevent students from taking startup disks from their lab computers.
Here are two methods:
1. Replace the Eject trap through an INIT so that the internal drive does
not eject disks.
(NOTE: This is not completely effective, since the user only needs to
restart the Macintosh while holding down the mouse button and the disk will
eject. The student could also use a paper clip to eject the disk manually.)
2. Physically cover the drive opening. This would be the preferred
method, since the student would not have access to the startup disk at
all. When the Macintosh was restarted the disk would reinsert itself
and the system would start up again.
Ergotron, Inc. makes a product, called "The Muzzle", that protects a
Macintosh SE startup disk, as do other third-party companies.
