I've just opened the case on my Buffalo hard drive, and the circuit just
says Buffalo. There's an ARM chip and a winbond chip, but not much else
to identify it. I'll ask around the USB-IF PIL lab to try and get a
company contact.

p.s. The Buffalo USB3 drive was much easier to open than the Dane-Elec
drive (and the hard drive and board was actually secured, unlike the
other drive). There's a screw on the top, and if you pry off the
stickers on the bottom, there's some plastic clips holding the case
together.
