* Any user areas you don't want or need can be deleted.
* Drive G: and H: are empty.
=== If your DIR just shows : characters (G: and H:) ===
There is a possibility of G: and H: not having properly setup directory entries on the image. When you do a DIR, you might see something like this:
G:>DIR
: : : :
: : : :
: : : :
: : : :
: : : :
: : : :
: : : :
G:>
If this happens, do the following:
G:>ERA *.*
..and answer y to the "delete all" question. This will sort out the directory.
