I have two 12TB HGST Ultrastar DC HC520 HDDs (HUH721212ALE600) from Western Digital that I wish to use temporarily in my desktop PC until I can afford to expand to a multibay NAS system. The motherboard is an Asrock X570 Creator with the latest BIOS update. I am using a 1200W Corsair PSU. The motherboard BIOS is unable to see either of the two Ultrastar DC HC520 HDDs. The disks do not appear to be spinning on power up. Any suggestions or recommendations?
