SATA drives not recognizing on GA-z170X-UD5 after M.2 Drive installed.

[Jawknee530]

I have two SATA HDDs full of data. I was running my OS off of a SATA SSD and just switched over to a Samsung 950 Pro which is M.2. I installed the 950 Pro and upron boot up none of the SATA drives are recognizing at all. Not even the DVD drive. I have windows installed and working fine on the 950 Pro but still no SATA drive access. Any ideas?

Check your manual because some m.2 drives disable some sata ports.
