This was sent me by Tom Shores, shores@fergvax.unl.edu.  Disclaimer: I
have not yet unBinHexed it, so I can't take responsibility for the
contents.  (No offense to Tom; probably, he didn't look at it either--
he had sent it to me directly upon pulling it off an FTP site, I
think.  I'm just paranoid, is all.  :-)

I'm posting it because I think it's a wonderful idea.  I'm sure it'll
save more than enough time/money (in lost man-hours of replacing
files) to justify the bandwidth.

Don't forget to cut my .signature off the end.

What follows was written by Tom.


BADInit by Giuseppe Carnevale.  This *WONDERFUL* INIT can save seemingly lost
floppy disks from the bit bucket.  Ever had a "File couldn't be written and
was skipped?" Of course you have, and this INIT fixes all that.  The INIT fools
the disk's desktop file into thinking that files are occupying the bad sectors
of the disk so you can write to the good parts of the disk too.  When you get
a bad disk that had been formatted and had files on it, salvage the good files
and tell the finder to reformat it.  When the finder fails, it will eject the
disk, but after you hit "ok" in the "Initialization Failed" dialog, another
dialog will popup asking you if you want to format it using BAD.  Hit OK to
work BAD's magic.  Likewise, with a brand new floppy that fails under the
Finder's initialization, BAD will format it, most likely leaving over 95% of
the disk still useable.  Obviously one wouldn't want to put one's only copy
of a doctoral thesis on the disk, but you can still use the disk for trivial
tasks.

(This file must be converted with BinHex 4.0)
