Asus b250 plus - second M2 SSD not detected

[jacke_]

Hi Guys,

I'm running my PC on Asus b250 plus mobo, with i3 7100 and GTX 1050 (if any of this matters). As main storage I'm using M2 SSD from Samsung, which works just fine plugged into M2 socket #1, and I have another M2 SSD plugged in into second M2 socket but no matter what I cannot make it visible neither in BIOS nor in Windows.

I tried to play around with some BIOS settings but I actually haven't seen any option about second M2 socket. When I switched SSDs's sockets I can detect the other M2 drive, but then Samsung one in M2_2 does not work. Seems like M2_2 needs to be configured somehow or some options needs be changed, but I have no clue where to get this info. Any feedback is greatly appreciated.

Cheers, Jack

Hi, The second one is SATA, or PCIe?

How can I find this out? Second one is plugged into M2_2 socket.. that's all I know for now

What exact model for both M.2 drives?

M2_1 - Samsung 250GB 850 EVO M.2 SSD
M2_2 - Transcend 128 GB M.2 SATA III SSD Type 2240 MLC

Both are SATA and according to the board's specs, only one M.2 slot supports PCIe and SATA, the other one does support only PCIe M.2 drives. That's why both do work in one of the slots.

Here:
1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (both SATA & PCIE mode)*2
1 x M.2 Socket 3, with M key, type 2242/2260/2280 storage devices support (PCIE 3.0 x 4 mode)
