As the title says, the SSD does not provide any SMART logs. The extended test is greyed out, and the short test appears to start but ends immediately after clicking the button. Last SMART test result: no self-tests logged on this disk. The drive is added as a pool device using Btrfs.

I would greatly appreciate some advice. The SSD is brand new, but it came in a suspicious ‘unopened’ retail box. Based on the code comparison, it appears to be original.

I had hoped it might be a general issue with SCM devices and how Unraid might handle their SMART reporting, since Samsung’s Z-NAND drives may depend on proprietary diagnostic tools.
