You can't mix ultra && LVD. They're one or the other (it's a voltage
thingie).

I've had experience with Quantum LVD drives and IBM LVD drives, but not
particularly under FreeBSD for a variety of complex && uninteresting
reasons. The drives I've had to play with are (they're now remote attached
to a Sun):
