If you have enough spare disk space, you may create the images of the disks using R-Studio, and then create a virtual RAID 10, then try to recover files from it. If there's no spare disk space, you may create a virtual RAID 10 from the real disk.
Here general conception on how to work with RAIDs: [url=http://www.r-studio.com/RAID_Recovery_Presentation.shtml]RAID Recovery Presentation[/url].

You may do everything with R-Studio in its Demo mode except saving recovered files. So, don't buy R-Studio until you have enough reasons to believe that R-Studio will recover your files.

My PC had an SSD as its c: drive, and a 4-disk RAID10 as its d: drive. I installed a new motherboard and CPU, stupidly assuming the RAID10 would just be there. The new machine instead saw a broken RAID0 (of disks 1 and 2), and two unrelated disks (3 and 4). So I reinstalled the old motherboard and CPU. And now the old PC config is also seeing a broken RAID0 (of disks 1 and 2) and two unrelated disks (3 and 4).

Somehow the new motherboard jacked up something (boot blocks??) on those two disks.

What is the safest way to recover using R-Studio??
