Just how much code does this take, and where can I find source?

Bob,
In "from scratch" projects I've done, I've always just implemented the
MS/PC-DOS FAT filesystem. It's simple, and it has the advantage of being
readable and writable from any regular desktop PC directly.
I've also done
several variants of *nix filesystems, which are
only slightly
more complex,
but perform much better at the expense of a bit of
RAM.
Naturally, if you
stick to the standards, you'll have no trouble
reading, writing (and
verifying the correctness of) these volumes from Linux or
FreeBSD. I prefer
