Question Can someone tell me why my motherboard isn't identifying my M.2 SSD?

[Bad Skiddy]

It's a Wacom Cintiq companion 2.

My old SSD died and I've replaced with a new one, but it just doesn't want to identify it so as i result i can't create a new partition to set up my OS.

Here's what i'm working with inside (from a break down Youtube vid):

and here's the old SSD and the new one I replaced it with:

Any help is appreciated.

So it turns out that the New WD drive doesn't want to read on any other PC I stick it in.
I guess I just got a faulty one from the batch. I'll update to see if my problem is solved when I get a NEW new SDD.
