Unknown USB bridge [0x04e8:0x61fb (0x100)]

[skoehler]

This is a Samsung T7 Shield, 4TB.

It has a USB to NVMe bridge. I don't know which one.

[Christian Franke]

Another Samsung T7 device reportedly uses an ASMedia ASM2362 bridge, see ticket #1403.

Please test -d sntasmedia option with smartmontools 7.3 or a recent CI build (​https://builds.smartmontools.org/).

I get the following when I try that on my Samsung T7 Shield, 2TB and 4TB.

/dev/disk5: Type 'sntasmedia': Not a device of type 'scsi'

This Anandtech article seems to indicate the use of ASMedia ASM2362 in their 4TB review unit.

I get the following:

Perhaps this is an issue with the the SAT SMART Driver and not smartmontools?
I'm using the one provided by Binary Fruit who makes DriveDx.

[skoehler]

You are using what? I'm using the standard smartmontools package (smartmontools 7.3-1) and the standard kernel (linux 6.3.1.arch1-1) on Arch Linux.

See ticket #1733 (4TB version).
