Updated description ------------------- Summary: The Buffalo USB3 hard drive fails to mount after being sent an ATA_16 IDENTIFY command. It does not fail when the device is connected via a USB 2.0 cable and the same command is sent. Details: There seems to be an issue with how the Buffalo USB3 hard drive handles the SCSI ATA pass through commands. We found this issue with the Linux userspace program hdparm, using the Ubuntu Linux Karmic distribution. The device responds correctly to an IDENTIFY DEVICE via the ATA_12 tunnel, but it responds with a Phase Error when it's sent an IDENTIFY DEVICE via the ATA_16 tunnel, and then stalls.
.. I hsven't gone away or anything -- still reading mostly every word of this thread. I haven't done anything further here because I really don't understand the whole story. Sarah's latest summary (above) helps a lot, though. But I'm not sure what, if anything I (hdparm) can do differently to help here. Can anyone out there send me one of these gadgets? Oh wait.. that wouldn't be terribly useful, I suppose, since I also don't have any newfangled USB3 host gear.
