Now that is interesting.  Always something more to learn.

I've been aware that the file system needed some way to avoid multiple 
attempts to use a block that has been determined as "bad", and the 
mechanism provided was the bad block file/list, so that the block would 
be "in use" and not free for re-use.

I wasn't aware there was an intermediate step.
