My problem sounds like that of AB1733, but my equipment is different: an msi 870U-G55 motherboard with an AMI processor, an Intel 530 Series SSD, and 2 Hitachi HDS721050CLA362 500GB HDs that are currently configured as AHCI, but which I would like to convert to a RAID+1 array. However, when I turn on RAID in my BIOS, I get a flash of BSOD and a reboot for my efforts. Are my efforts in vain? 1) Can the Hitachi's be used in RAID? and 2) is it possible to use the SSD as a single disk with the RAID+1 array, without reloading everything?
Odds are that in switching the controller to raid moe that the controller the ssd is on is also being changed to raid mode. Passing the single disk thru is typically possible but you will need to review your motherbds documention to find out what you need to do in the raid bios to pass it. Sometimes there is a single disk option, other times you need to create a single disk raid1 or jbod. Please note that this may mean reinstalling the OS
