I just upgraded my computer, my new motherboard (MSI Z370m Mortar) has two m.2 slots. The top m.2 slot isn't reading my m.2 drive. When I install my m.2 drive in the bottom slot it reads it but the bottom slot only has a screw hole for a 2280 m.2 ssd and I have a 2242 m.2 ssd. I don't know a lot...
