Since cluster sizes are multiples of 512 byte sectors, this does not seem
possible, but even if it were, fragmentation would be the least of your
problems - your FAT would then contain 1.5 bytes for each byte of allocated
file space, it would no longer fit in memory (unless you had a real tiny disk),
thus file access time would really bite....
