Dead drives are usually dead and gone. I think I've seen a handful come back in decades.

I just built a new computer, and the hard drives are not working. The spec are as follows:
CPU: i5 4690k
Motherboard: Gigabyte GA-Z97X-UD3H
SSD: Samsung 120 gb m.2 drive
HDD Western Digital Black 1 TB (x2)
Ram: 8 Gbs Corsair Vengence 1600 mhz
My issue is that that the bios isn't picking up either of my new WD drives. The SSD came up, so i was able to install windows, but neither of the drives are. Did they both fail? What do I need to do to get these drives working. Any help is appreciated, thanks.
