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. Sarah Sharp 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.
