I am building a new rig and trying to RAID 0 my two 120gb SSD's. I have a Asrock 990fx extreme 9. I have raid enabled in bios. When I try to install windows 8.1 on them it says they are not formatted. Windows installer does seem them as One drive of 221.8 GB. When I hit CTRL + F during boot and get the old school dos menu for raid. It has them as two separate drives. In that mode there is no options to change them or choose anything about RAID 0. I tried putting my old drive with windows on it and try raiding them in windows and when i was tried to format in diskpart the system crashes and get the blue screen. What am I doing wrong? Is there something I am not setting up in bios? Any help will be well accepted.
