One fundamental point is that you *can't* have that many 'primary'
partitions on a disk; the limit is four. You could have your C D E and
then make the fourth an 'Extended partition' containing F G H as
'logical drives'

Second point is that your 80 GB is measured in decimal billion;
partitions are in a binary near equivalent; 1024*1024*1024 or about
1.073 billion, so your drive will appear as about 75 GB

Third is that DOS, and its tools like FDISK, do not like having more
than one regular primary visible anyway. and will give difficulty with
your D. Presuming that you do not want two separate DOS *systems* and
that D is intended for data to use with the DOS in C, then make the
arrangement Two primaries; one 2 GB for DOS: one for Windows XP; and
the rest of the disk as an extended, putting your 2 GB for DOS data in
there, too. DOS will then see the 2GB primary as C;. the one in the
extended as D:. If you install XP into the second, bigger primary it
will see *that* as C and assign letters to other partitions which you
can adjust in Disk Management. Drive letters are not absolute things,
but get assigned by the systems as as they boot
