DFIX Copyright (C) 1985, 1986 Howard Rumsey Jr.
DFIX disk fix utility. Reads the whole DOS partion on a disk (floppy,
hard disk, ramdisk) and, if directed, marks bad clusters in the FAT(s).
Usage:
dfix [d:]
d: is an optional device specifier. If not specified DFIX will
use the default device.
If DFIX finds a bad cluster already allocated to a file, this will
be reported and no further action taken. If DFIX finds an unallocated
cluster, DFIX marks its local copy of the FAT. At the end of the testing
the user is asked if he wishes to permanently mark the cluster as BAD.
DFIX is a substitute for the disktest program included with Version 3
of The Norton Utilities (tm). The Norton package contains many other
useful tools. I wrote this program and am placing it in public domain
because of its (sometimes) critical value.
This program may be freely copied and used for any non-commercial
purpose.

v1.2 Toad Hall Tweak, 7 May 91
Slight touches for Turbo C compile.
Reformatted to a "normal" indentation, etc., ala K&R.
No functional changes.
Works fine on my good old Seagate 20 megger, no promises
for any of those big suckers, non-MFM drives, etc.
Oh .. you'd better use the TCCONFIG.TC I'm including in the
package. The main reason: byte vs. word alignment. If you
use word alignment, the structure comes out wrong! Trust me!
Or, under TC's options, just set the compiler data alignment
to "byte" rather than word. Suit yourself.
I don't quite understand how an author can give a program
to the public domain, yet maintain copyrights and distribution
restrictions .. sigh .. guess the "Public Domain" definition
has changed somewhat.
