The problem is that there are two kinds of disk devices, and
HARDDISK_VOL should only be used for things that have an actual device
associated, i.e. USB sticks and the like. Currently there's no way to
make that distinction in winecfg or in the registry.

I don't think we want to extend the existing mechanism because the
registry config needs to be changed anyway. There's a lot more
information that mountmgr needs to store beyond just hd/cdrom/floppy,
and extending the current scheme will only make it harder to change
while maintaining backwards compatibility.

Though I'd expect the current behavior to work fine since the harddisk
type is autodetected. Is there really a need to configure an explicit
HARDDISK_VOL device from winecfg, or is it just because it's there in
the winecfg dropdown?
