The size on disk is rounded up to the block size of the filesystem. If you
have a cluster size of 2K, then even a 1 byte file takes 2K.

The cluster size is different, usually smaller, for smaller filesystems. A
floppy has fewer and smaller clusters than your hard drive, therefore, the
on disk size will be smaller.

I'm not at my Mac right now, so I can't give examples of my settings. I also
can't speak about 8.1/HFS+.
