Mac mini 2 internal drive no longer showing up in disk utility

I attempted to update to 10.10 and half my software didn't work right so I decided to attempt a downgrade.

Long story short...my 2 internal hard drives, SSD and 7200rpm disk, no longer show as separate drives on disk utility

It seems they might have been summed virtually into one drive? The language I see is "virtual whole disk"

In the disk utility list there is also a "disk2" with a picture of the world over the disk icon. I assume this is the virtual disk used to reinstall from the Internet?

Either way, how do I get my separate hard drives back so I can use the SSD for my boot drive?
