I was searching and came across testdisk, seems like a handy tool. I've never used it before and just wanted to make sure I am doing the right thing.
My motherboard is MSI Z87-G43 GAMING, and I am using it's included raid controller, Intel Rapid Storage Technology.
I am currently running a quick analysis on both drives individually but I am not sure if that is the correct thing to start with. If I load up test disk, this is what I see:

The drives in question are the two 4000 GB ones. But there is also drive D which I am assuming is original raid partition? How should I go about recovering?
The data on these drives is not incredibly important, nothing I can't replace. I'd like to try and recover it though if possible. And, why raid 0? Because. lol. I had never set up a raid before and figured if I lost it then no big deal.
Thanks!
