Discussions on using the professional data recovery program R-STUDIO for RAID re-construction, NAS recovery, and recovery of various disk and volume managers: Windows storage spaces, Apple volumes, and Linux Logical Volume Manager.
I've done that and made images of 3/4 drives. The 4th was replaced but hadn't rebuilt.
Weeks of playing with settings in RT hasn't generated a working set of files from images or the disks. I suspect something unusual about the AMD RAID isn't known to the RT software.
