<Prevents accidental Erasure by Line-Eater>
The following proceedure has proven useful in preventing accidental
erasure of hard disks in MS-DOS systems.
1: Rename FORMAT.COM in your DOS directory to KILLDISC.COM
2: Place the following file as FORMAT.BAT in the DOS directory
This little ".bat" file has saved more than a few hard-disks from
premature distruction. It is transparent to the user except:
1: Drive C: cannot be formatted by the "format" command
(Note that killdisc IS the old format command so the)
(capability isn't lost: "killdisc c:" works. )
2: There must be a space between the drive name and the
switches (e.g. "format a: /s" works but "format a:/s"
doesn't).
It is simple and somewhat inelegant. It is also extremely
useful! Any modifications needed for your system should be
clear. It is configured for a one floppy (A:), one hard-disk
(C:) machine.
