USB drive letter designations changed

I installed daemon tools 347 so I could check a bin before burning. So I got to playing around with virtual drives and their designations
Somehow in my noobness, I got my USB hard drive (WD 80G) letter designations screwed up...

Before Daemon, I had two partitions on this HD named:
USB HD (F
USB HD (G

After playing with Daemon, they ended up named:
USB HD (F (G
USB HD (G (H

I tried renaming back with disk management, and ended up like this:
USB HD (F (F
USB HD (G (G

I'm not sure what is going on here, or how to get my original single letter designations back...

In order for all everything to work again, it must be changed back exactly, ...ie, must say USB HD (F/G in explorer...is that right? Because I think I can rename the partitions to just (F and (G, but no facility in disk management for the "USB HD" part, which got tagged originally when windows recognized the drive when i first connected it.

Any help would be appreciated...thanks in advance. BTW, I'm running xp home.
