So i recently upgrade my case and motherboard and in my old pc all drives worked fine. Now in this system the SSD's are both connected and detected, but the HDD isnt. I've tried everything, I replaced the sata cable, I've used a different SATA power cable, I tried putting in a different drive that I also know works (also not detected), I changed SATA ports on the motherboard. Nothing I do seems to help or have it show up in the BIOS. I'm at a complete and utter loss.
