[SOLVED] I cannot see my nvme m2 ssd.

Hi,
I'm using Xiaomi notebook air 13.3 that already had 256GB m2 ssd (m key connector). It has one free m2 slot (b key connector) so I bought another drive (480GB m & b key connector). M & B key should be compatible with either m key and b key connectors, but it's not working. Even Windows cannot see it. Is it really compatible and if so do you know where might be the problem?
It seems that my motherboard doesn't recognise it because:

Where nvme0n1 is that original 256GB SSD

Re: [SOLVED] I cannot see my nvme m2 ssd.

Doesn’t sound like a Linux problem.  Does the BIOS see the 2nd one?  It there some option in there you need to enable?

There is no option for disabling/enabling hardware. In Bios, I can display just bootable devices so because It's a new disk I cannot tell whether Bios recognises it.

Re: [SOLVED] I cannot see my nvme m2 ssd.

I've found few reviews about m&b key compatibility with my notebook and it seems working together.
It's possible that I have damaged disk. So if I could ask for way to distinguish between these scenarios (damaged disk, incompatible MB, problem with OS).

Re: [SOLVED] I cannot see my nvme m2 ssd.

Look in dmesg for clues.  Boot from a live environment with the funcational disk and compare dmesg output there to booting with the other disk in the same slot if that is possible.  Then boot sith both installed and again compare.

Re: [SOLVED] I cannot see my nvme m2 ssd.

Tried that and I could find any traces that I have plugged another disk. However I was able to find this disk in Windows (I know it's super lame to have windows on your machine, but I like to play games.). Arch found it too after formatting it to NTFS with some weir built-in Windows application.
Thanks for Your time and advice. It looks like software problem after all.
