Can't rename subst drive in Ultimate 32-bit

I just set up a RAID 0 array out of 2 WD Caviar 320GB's. I have the
one giant drive with some subfolders (Games, Video, Music, etc.), and
I like to have a G: or Games drive.

So I used SUBST and created myself a G:\ drive going to D:\Games. Now,
the name of the big drive is Storage. This new virtual drive is also
called Storage, by default. I right-click and Rename, and type Games,
nothing happens. Drive name stays the same. Try doing Properties and
filling in the name that way, nothing, won't stick. Can't get this
darn thing labeled.

Any tips?
