I change my old computer form FX8350 in AM3 to R7 1800X in AM4 and my Raid 10 isn't detected correctly. I have 4 drives and not only one. In the disk manager of Windows, I have 4 drives with one in error "signature collision" (see screenshot). My drives are connected in the same order on the same SATA of the motherboard (SATA 1 to 4).
My old motherboard was a MSI 990FX Gaming, the new is a MSI X370 Gaming Pro Carbon.
I use Windows 10 Pro Anniversary Update with the drivers installed by Windows (fresh install).
