Yeah, I unplugged my old drives & it switched on fine, booted into windows. I then plugged in one of the old drives, popped into the bios & noticed that the secondary HDD wasn't showing up (the power cable had come out). Now I'm back in windows & copying over all of my stuff from the old storage HDD & will try with my old SSD when that's all done (which may take some time with ~133 gig....).
