Would you like some remote assistance?

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.

As I understand, this is a built-in RAID controller. Somehow the RAID had failed, and you (or the system) created a new one.
You definitely should disassemble the RAID in the RAID controller and create a virtual one in R-Studio out of the drives from that RAID. R-Studio's help: Basic RAID 4 and RAID 5 Operations. RAID Recovery Presentation.

For the record... the drives are in a cage so any change in order is a total reverse and not some random change.

I would guess that the RAID was re-assembled using the wrong drive order or configuration.

You'll need to connect the drives independently (not as part of a RAID) so you can work with them in R-Studio. Nothing you can do through the RAID card in RAID mode, as it's trying to automatically destripe the data using the wrong config.

I'll PM you my contact details so we can chat more about it.

I've not solved it at all.

For some reason I can see the whole failed RAID set up now as opposed to just the disks. Somewhere along the way something has "fixed" itself. All which is odd given this screenshot.

Here is what R-S sees...

Unfortunately nothing recognized creates a working file.

I haven't given up yet...

I've tried it once or twice, but it is just easier to remote control the system and run R-Studio locally.

Auto detect only works in some cases, and from what you're describing I doubt it'll correctly detect the settings. This is a case that'll need some manual expertise. If you haven't solved it yet, please message me and I can hopefully guide you further.

Also I'm scanning 3 disks this round using 3 sessions of the software. All while using the browser and other programs.

Task Manager reports
CPU ~40%
3 disks at 90%
4/16 Gb RAM

These is some scope here to not just batch this process but to run multiple scans on different disks simultaneously. At least 4 seems very possible.
