Samsung Magician 6.2.1 correctly recognizes my 970 EVO M.2 drive, but when I click on Diagnostics it tells me that "The selected drive does not support this feature."
I have updated the drive to the latest firmware, and installed the Samsung NVM Express Drive 3.3.
Any thoughts? Thanks in advance!
i was having the same issue with my samsung evo 970 plus nvme device. i found that installing the samsung nvme driver solved that an that i can now run diagnostics using samsung magician software. (SSD Tools & Software | Download | Samsung V-NAND SSD | Samsung Semiconductor Global Website)
