It's easy enough to do, as long as you have something to edit the
partition table with. I'd recommend Supra's SUPEDIT program; it's a very
nice hard disk editor that lets you access the raw data or will let you
edit it in interpreted form. (When mucking with partitions, I definitely
like the latter so I'm shielded from really gross mistakes.)

Just check the table entries, say you have C & D with
     beginning  length
  C    0        10000
  D   10000     20000

and you want to split D - simple. Just change the entry for D:
  D   10000     10000
  E   20000     10000

Of course, if those blocks toward the end of partition D are actually in use,
you'll have some problems...

You'll also have to change the parameters of each partition's root directory.
That's another menu in SUPEDIT - shrink the size of partition D appropriately,
and create an appropriate root block for partition E - just copy the values
displayed for D. Finally, zero partition E - that will initialize the root
directory properly for regular use.

On second thought, you should probably also back up D before doing all this,
then zero D when you're done, and restore whatever files you want.
