i have recently bought 2 crucial 256 gb drives,replacing 2 64 gb patriot drives.i ran out of space on my patriot drives.and since then i been having problems with mobo set features like instant boot and atux.which are features downloaded to mobo.contacted asrock and stated most likely corrupt file in windows.got tired of inconsistency and made move to do new install of win 7 pro,with my 2 new ssdh,but they are set up in raid o,and i need to partition and format them before my win 7 arrives. since in raid o do i format both ssdh and set partitions for win 7 on both .or just one sshd,and just format the other. or just wait for software and do it then. looking forward to get my computer running right.thank you vanniko63
