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.
..
Okay, apparently the shop around the corner has some $25 USB3 interface boards
for PCIe, and also some for ExpressCard on my notebooks.
Now I just need one of the buggy USB3/SATA bridges to test/debug with.
I'm not willing to spend much of my own money on something known to be buggy though.
Anyone out there got one they could loan?
Cheers
