I likewise couldn't find a reference to the BTM _or_ the author on the net.

I did find a "munged" version on an old floppy diskette and it looks like I
was attempting to modify it for some reason or other...  I'll post what I
have and maybe some people can jump in to get it cleaned up / improved.

As you can see, Christopher was not very detailed with the docs...

The main reason I wanted this BTM was to hack apart the CHKDSK section.  I
don't particularly like doing an indiscriminate CHKDSK /F because I prefer
to know if chkdsk found a problem first (and what particular problem) and
then determine if the "/F" will correct the problem(s)...

Also, depending on the severity of the problem, it may not be entirely
necessary to run SCANDISK. ???

           Cheers ... Gerald

.... One day, I may actually understand all this techie stuff......
