Go to the Microsoft web site and search for the document called
"fatgen103.pdf" which will tell you everything you wanted to know about the
FAT filesystem and the pitfalls people have in trying to emulate it. If it
cannot be found then it may have had a later revision, in which case search
for just "fatgen".

I would strongly recommend this as it has example pseudo C code, and also
gives examples of how not to do FAT files, and why some people have problems
with the way they do it.
