I have a 4-disk RAID10 volume managed by Intel's on-board controller and want to downgrade to a 2-drive raid. My plan is to remove the two mirrored drives, make them into a RAID0 volume, and migrate the data. The trouble I have is identifying which of the disks are the mirrored disks. There are no indicators in the IRST management software, and I can't tell if data is stripped across disks 1 & 2 and mirrored in 3 & 4 or stripped across 1 & 3 and mirrored in 2 & 4.
