Thanks to Stephen Trier for pointing this one out to me.

Meaning that hd will currently work only on text files :-(
Here is a context diff that will cause "patch" to change hd.c, all that is
needed is the -DMSDOS flag added to your msdos makefile.
run:
patch -c hd.c patchfile
If you don't have patch then there are NOT a lot of changes to make by hand :-)
Thanks again to Stephen
Keep Enjoying!
Pete.
