HDD Question

[fantasticCG]

Hi im running windows on an SSD.
Ive just put back in 2 500GB drives in my pc they dont show up under my computer just the SSD. They show when booting up and they show in the bios
any ideas?

They where in my old system and in raid if that helps, the raid was not done by myself
