Description (last modified by )
I have a 3 TB Seagate Expansion portable USB 3.0 hard disk:
https://usb-ids.gowdy.us/read/UD/0bc2/231a
, model should be STEA3000400 (as found in an XML file which came inside the hard disk when I bought it)
with the suffix SRD0NF1 I guess (from the sticker in the back of the hard disk)
With UAS enabled I can see info with -d scsi (-d sat{,12} doesn't work), but SMART info is not available:

If I blacklist UAS, then I get from smartctl:

I wonder if it's possible to get SMART access without blacklisting UAS. I don't like the "very big device" messages I receive in dmesg and I guess the device will perform better with UAS enabled (Kernel 4.14.15-1 from Archlinux X86_64).

No kernel messages triggered in both cases.

This suggests that the USB bridge does not support SAT ATA PASS-THROUGH when in UAS mode. Cannot be fixed by smartmontools.

Is there anything that can be done at the kernel driver level to query the device in BOT mode while the UAS is enabled? I wonder how in Windows it's possible to query the SMART info while it's still in UAS mode (AIDA64 can do it for example).
comment:6 by , 7 years ago
Same issue was reported for similar drive with Id 0x0bc2:0x2322, see ticket #973.
Note that various Seagate devices are listed in the unusual_uas.h file of Linux kernel. Which means that various aspects of UAS are broken with these devices.
Is there anything that can be done at the kernel driver level to query the device in BOT mode while the UAS is enabled?
No (AFAIK).
I wonder how in Windows it's possible to query the SMART info while it's still in UAS mode
Did you try smartctl for Windows in UAS mode?
(AIDA64 can do it for example).
Note that vendors of such closed source tools could sign a NDA to receive proprietary info from OS or device vendors. Open source developers could not.

I have tested smartctl both on Linux and Windows, with Seagate Expansion USB 3.0 1TB drive 0bc2:2322.
On Linux, since kernel 4.14 all Seagate enclosures have ATA passthrough disabled when using UAS (https://github.com/torvalds/linux/commit/7fee72d5e8f1e7b8d8212e28291b1a0243ecf2f1). So, smartctl does not work when UAS is enabled.
But, on Windows, smartctl works correctly and uses ATA passthrough (16) in UAS mode (I have verified this using a USB sniffer, it definitely uses UAS, not USBMS).
So it seems the only problem is that in the Linux kernel all Seagate enclosures are treated as if they always have broken ATA passthrough.

| Summary: | UAS support for smartmontools → No SMART access to Seagate devices under Linux if UAS is used |

Thanks for the info.

| Milestone: | undecided |
|---|---|
| Resolution: | → invalid |
| Status: | new → closed |
Linux 4.14 or later disable SAT ATA PASS-THROUGH to devices with USB Vendor Id 0x0bc2 if UAS is used. See above for details. This cannot be fixed by smartmontools.

Thanks everyone. Everything's clear now. If someone Googles about this problem, hopefully they'll find this ticket. I was lost about what's going on when I opened it.
comment:12 by , 7 years ago
Nice! I sent an email to a kernel developer and he told me that although Seagate is making improvements, although there still are broken devices so the ata-passthrough in UAS mode ban will be kept in place. He implied that I was lucky if a Windows tool managed to access the SMART info of the device with that firmware bug.
He told me too how to disable the UAS quirk, which I did, and now I can access the SMART info in UAS mode. It seems this hard disk model from Seagate doesn't have any firmware bug.
The method is adding the same as adding a USB quirk to a device but without the ending letter which defines the quirk to apply, i.e. no ending letter means "no quirks" for this device. In my case, I added to the kernel command line: usb_storage.quirks=0bc2:231a:
So, thanks again to everyone involved!

Thanks for this post! I did indeed find it via google, although not via duckduckgo :-(
Note:
See TracTickets
for help on using tickets.
The USB bridge might support SAT ATA PASS-THROUGH command only in BOT mode, but not in UAS mode.
Please provide output of
smartctl -r ioctl,2 -d sat -i /dev/sdbas an attachment to this ticket. Add kernel messages triggered by the command (if any).
