My ASUS TUF motherboard does not read second M.2 SSD

As both your M.2 drives are NVME the issue of a SATA drive in M2_1 does not arise. In some Asus motherboards there was an option to set M.2 slots to either SATA or NVME although the normal setting was AUTO.

One of the screen shots you supplied has your SATA Mode Selection under Advanced/PCH Storage Configuration set to 'Intel RST with Intel Optane Syst..'. In addition M2.2_2 PCIE Raid Storage Support is set to 'Not RST Controlled'. If the system won't support both an RST controlled M.2 and a non-RST controlled M.2 at the same time I would expect that you could use M2_1 on its own, M2_2 on its own but not both together. It might be worth seeing if you can set these two settings to the same RST control status, it could be a potential solution.

Edit: It may seem a contradiction to say that the issue of a SATA drive does not arise, and then talk about the SATA Mode Selection setting. It's the reference to Intel Optane that's the clue. To keep it simple, Optane drives were NVME drives that created a bridge between themselves and a SATA drive connected to one of the SATA ports. To enable the Optane drive you had to set the SATA Mode Selection to the setting you have. The second thing was that the Optane drive would only go in the M.2 slot that was connected to the chipset. On your board this is M2_1. The other M2_2 slot on your board is connected to the CPU. Your boot drive should go in M2_2 and your storage drive in M2_1.

Optane drives did not appear in the BIOS or Windows which is why it may help to set the 'Intel RST with Intel Optane Syst..' setting to something else that hopefully makes the drive visible in the BIOS and Windows.

Hello, the setting you reffer to is AHCI by default and is what I have set now aswell, when I set Intel RST optatne…not RST controlled - my boot drive in M.2_2 only shows up, when I choose RST controlled not even that shows up. Playing with these setting was among the first few tries of fixing this issue and even if I dont really undersrand what these settings mean, whatever option I choose, my M.2_1 slot drive just wont show up anywhere.
 
Please Read this, this is your motherboard manual.

Here is your manual.


Do a Clear CMOS and see if your issue resolves, if not remove the WD drive, im unsure if the WD Drivehas been formatted as SATA or is firmware configured for SATA or of the motherboard configures the mode of the slots.
 
I was looking into usb adapters for nvme and it would be probably the only option to put that ssd to some use at least, since I am not planning to buy a new motherboard anytime soon.


Yes, I attached picture of this part of the manual when starting this thread I am just not educated on this topic so I didnt know what to really make of it.
You can run two NVME, or one NVME and one SATA in those M.2 slots

M.2 is a size

M.2 slots do not always support SATA, it's optional
