I'm not sure which is better for performance :p

If you have 51198 clusters, then you only need 200 sectors of FAT.
So, this is probably a M$ work-around.  I'm too paranoid to put this
in Parted, because other versions might do different (incompatible)
work arounds, or something...  But, it's good to know... maybe
we'll understand this better in future...

(If you're thinking "it can't be THAT bad", look in
libparted/fs_fat/calc., near where it says DO NOT CHANGE THIS ALGORITHM)

Also: it says it's a "32 bit" file system.  I have no idea what that
means... but it's FAT16.

It uses the Linux versioning scheme, but 1.2 and 1.4 should both run
on linux >= 2.0, although I haven't tried anything other than 2.2 for
a while!

1.4 introduced a nicer internal API for disk labels, which means we
now support Mac, PC98 and BSD.
