This is why I don't use RAID. It's such pain in the ass and frustrating when something goes wrong.
I used to have RAID 0 on my 2 500 GB Hard Drives. It worked all fine until I decided to install some other operating system (well, ok, it was Linux, Fedora to be exact). One thing I didn't predict was the fact that once I installed Linux, getting rid of it would be tricky. It all worked fine until I decided to remove it (don't ask why, I can't remember, I think I installed it because Windows was screwing up and I figured I'd try to install it back). Well...I tried, but then I couldn't boot onto anything (all I got was a black screen).
Fortunatly, all important data I had saved on these drives was backed up so I could safely terminate that RAID...or could I?
Well, I couldn't.
I couldn't format these drives with recovery console and I couldn't reinstall windows. I couldn't get rid of RAID from BIOS side because that friggin app that was supposed to do it didn't want to launch. Hell, even the BIOS menu itself decided to crash on my face, first time I ever seen that.
Hardware was still on warranty and I didn't want to void it just to get rid of it manually.
I'm not bad at PCs myself, but I was completly stuck. The only way I could fix that was by paying a visit in PC service where I got the hardware from. The RAID was removed and everything worked fine since then.
Now I only use 3 Hard Drives, of which 1 I use for operating systems, 1 for Data storage and 1 for mirror of said data storage. Oh yeah, and I have Live Linux on USB stick, its less problematic that way.
