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 (

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.

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.

comment:5 by skoehler, 12 months ago

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.
