Here is a quick fix for FORMAT on DOS 2.0 to prevent accidental
nuking of the fixed disk.

debug format.com
-d 7c7 l1
XXXX:07C7  74                     <debug responds with this>
-e 7c7 72
-w
-q

This changes a jump condition so that FORMAT responds:

Insert drive C and strike any key

when you try to format the fixed disk.  Typing control-c
or break will then cancel the format (non-believers can
turn the PC off to be sure).  A bizarre way to "fix" the
problem, but it works.
