Question Asrock Z370 Tai Chi M.2 port issues

[ShuDog]

Hi,

In regard to my Asrock Z370 Tai Chi Motherboard, I have 2 identical m.2 drives, the only port that will recongnise them is m.2_3, neither of the other 2 will show them in the bios or windows drive manager

I have tried both drives in all ports and both only work in m.2_3

I have unplugged all SATA devices so there is no conflict issues.

I have 2 x WD SN770 2TB M.2 Drives

Bios is 4.20 and has been reset and restored to defaults, can unyone help please, its looking like I will have to send one of the drives back as the board maybe faukty, tho its seems strange 2 ports would fail.

Any ideas would be greatly appreciated

Cheers

Shu

It's not strange, because both ports utilize the same bus and controller. RMA the board if they work in one slot but not others. Unless you have SATA drives attached that nullify those particular M.2 slots, but I don't think that's the case in this case.
