Hello, my 1st thread in here.
I have an Asus B660M Gaming Plus Wifi D4, a Samsung EVO 970 installed in the M.2_1 slot (with Windows in it) and it's working fine, my 2nd SSD is a Kingston SNV2S/500GB installed in the M.2_2 slot on the motherboard (I used it mainly for storing games).
The 2nd SSD is now not detected in BIOS. I have tried to restore default in BIOS setting and while it did recognize the SSD but only a few hours later the SSD is not detected again.

Does anyone have a clue and how to fix it? Thank you very much.

I've tried that, didn't work. When the SSD is suddenly not detected anymore it shown this in Event Viewer.

Can you test the ssd on another pc?

Post a screenshot from crystal disk info for the ssd.

Make sure, sata controller is set to AHCI mode (not Intel RST with Optane).
Make sure Intel RST is disabled.

In simple BIOS mode - there's a toggle switch to enable/disable Intel Rapid Storage Technology. Set to disabled.
In Advanced mode - Advanced/System Agent Configuration/VMD setup menu/Disable VMD controller.
After doing this I ran into Inaccessible Boot Device so what do I do? Have to re-enable the IRST to be able to boot into Windows
