M.2 SSD Issue Pls HELP

[Ulysseus17]

Hey all, 

So I have a total of 3    M.2 in my system currently. One is a 960 evo which is my boot drive, and the other two are attached temporarily to an dual PCIE m.2 expansion card. Long story short is both of my m.2 in that expansion card are recognized by my BIOS, and by device manager in windows. The issue I am having is that Disk Management is only detecting and allowing use of one of the M.2. They are Western Digital Blue m.2. I have tested both M.2 on a separate system and have no issues. So I know both drives are good and I also tested the expansion card on another system as well. 

 

The purpose of my using this expansion card is to eventually set up an SSD Raid. I wanted to test it first with a couple before I go spending money unnecessarily. Does anyone have a suggestion on what I may be able to do in order to solve this problem. It is very frustrating, and at this point even google has failed me I checked there too. *sad face*

System specs?

You might not have enough PCie lanes - what CPU do you have?

Unless that expansion card has its own RAID controller you likely need to tell the slot that it is plugged into that it is actually 2 slots (8+8) or 4 slots (4+4+4+4).

 

You want to check that, your motherboard is capable of PCIe bifurcation, that the card is plugged into one of the slots that can do this and that the slot is set to that mode.

What is the make and model of the expansion card? If the card does have its own controller it might have a jumper that is setting its mode automatically.

Looking at your motherboard you have 3 M.2 NVMe sockets, why not just use all 3?

I am going to switch too the on board m.2 I just didn't want to have to remove the graphics card. Due to water cooling. However looking at the expansion card it did not have a raid controller. I think to avoid the issue I'll take your advice and switch to the onboard m.2 rather than the expansion. Thank you for the reply.
