smart not supported on external hdd maxtor m3 ?

[IRn]

The Maxtor M3 2,5" 4TB external HDD is listed as supported: https://www.smartmontools.org/wiki/Supported_USB-Devices

I tested:

sudo smartctl -a /dev/sdb
smartctl 6.6 2016-05-31 r4324 [x86_64-linux-4.15.0-33-generic] (local build)

/dev/sdb: Unknown USB bridge [0x0bc2:0x61b7 (0x000)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

I need smart on my device, can it be solved?

Should work since r4685 which was merged in r4692, see ticket #1077.
Please run update_smart_drivedb or download the drive database manually.

In UAS is enabled, Linux rejects SAT ATA pass-through to Seagate USB devices. See tickets #971 and #1069 and USB wiki page for details.

Same error with the current version.

This is as expected if UAS transfer mode is enabled, see comment above.

Replying to Christian Franke:

This is as expected if UAS transfer mode is enabled, see comment above.

Can you provide an example for blacklisting uas.

from dmesg output:

Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.15.0-34-generic root=UUID*** ro splash quiet vt.handoff=1 uas.blacklist=yes
uas: unknown parameter 'blacklist' ignored

The kernel parameter 'usb_storage.quirks=0bc2:61b7' does not work as well.

Thank you!

[Christian Franke]

AFAIK (not tested):

• usb_storage.quirks=0bc2:61b7:u disables UAS transfer mode,
• usb_storage.quirks=0bc2:61b7: disables all quirks.

Both should enable SAT ATA pass-through. The latter might be risky as kernel developers disabled it in UAS mode for some good reason.
