The ARM chip in the Buffalo USB3 drive is the USB3-SATA bridge MB86C30A by Fujitsu: http://www.fujitsu.com/downloads/EDG/binary/pdf/catalogs/a04000431e.pdf My guess would be that any drive using this chip will choke on the identify command. Sarah, any chance you could get a contact at Fujitsu? -Jonas
