Adding 2nd HD

[FGASo]

I am trying to add a 2nd 2TB SATA HD on top of the existing 2TB SSD on my new laptop. When I open the case I see that there is a location to add a second HD. I order the case and cable, connect the HD with the cable, the laptop does not detect the HD. I ran Windows memory Diagnostic, to help detect large HD, still not able to find the second HD.
When I connect that HD to an external bay, I am able to see the HD.

I purchased and tried the following connectors, all unsuccessfull:
