I have one in my Linux system desktop, the motherboard didn’t have the slot so I bought an adapter made it works. But boot the OS from it I still don’t know how. Online find some resource about Windows OS.
I see,
try format it or connect to a known good computer test again.
@Sphinx Yup, that's what I was doing when I got that Sense readings.
Looks like I get to hulksmash a NVME!
