Question "A device which does not exist was specified" error

Apr 14, 2022
Hello! I've got a problem with my m2 nvme ssd (ADATA XPG SX6000pro) suddenly i got this message from the image while trying to access the files inside the drive, I already have the latest version of bios, my motherboard is gigabyte b365m fyi and I cannot find a solution, honestly i don't know if it's about my m.2 slot because i don't see it everytime in "My Computer" sometimes i see it and sometimes not. I also tried to check the errors by that from, proprieties but as you can see in the image it doesn't seem to work.
I also gave it to a friend and for him it works perfectly, what would be the problem?

My PSU is Seasonic S12III-550W and i have it for about 6months.
In disk management i am not able to see that drive, but the others are perfectly fine. (Imgur: The magic of the Internet)

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition.

Disk drive(s): make, model, capacity, how full?

Are you able to access the Disk Management screens?

If so, expand the window to show all drives and included information.

Take a screenshot and post the screenshot here using imgur (
