I am having trouble with my intel 660 2 TB m.2. I initially formatted it and if worked just fine, but in the past week or two I can't seem to find it anywhere but in bios. I have tried updating drivers and everything else that I could.

I got this m.2 about a month ago and it has worked fine until recently. I have uninstalled and reinstalled the drive i have looked thorough disk management and it dose not seem to appear anywhere in windows but it dose seem to show up in bios.

Did you by any chance, accidentally or on purpose, disable UEFI boot in BIOS Setup? I would check BIOS Setup to be sure; UEFI boot is a requirement for M.2 NVMe SSD support.

Hope this helps,

So I figured it out but it's quite anticlimactic. It was a driver update. Now I tried this same update on atleast 5 separate occasions but it always said I had the most up to date driver. Now I do it and suddenly within 3 seconds I can view and acsess my m.2 like nothing was ever wrong with it.

I am glad you have it working, but I am doubtful that this was the issue.

I think the underlying issue might have been with the new windows update as the timeline seems to match. Regardless it's working for now.

Yet another driver screwed ​up during a Windows 10 upgrade? Why aren't I surprised...
