I got 4 2TB hard disk drives that were originally striped together in a Raid 10 (I think)... the problem is now I just have a mess, and given that my laptop with my backup got stolen. So I tried to access the drives in my PC (which had been unplugged, I span them up only for making backups) but this time, the one time I needed them... they did not show up properly, adding to the mayhem of issues I have been having. Now my question is, can anything be done? There seem to have been 2 4TB partitions on the four drives. All the bits seem to exist, but neither I, nor my computer know how to stitch it back together into a cohesive whole. I tried reassembling the RAID in the BIOS, but it would not let me do anything without wiping the drives. I scanned all four with Testdisk, and well... the results are below. I am still on that screen, not gonna do anything without input from someone who knows this stuff better.

Edit: If it helps, the drives were striped together using a AMD RaidXPert2 utility in the bios.

TestDisk only supports some Linux RAID structures but not proprietary other ones.
I don't use RAID. You do not know for sure which RAID level you installed.

Use same RAID recovery software, there is nothing I could help you with.

I just finished recovering some files from my 2Tb raid 1 disk which came out of my Qnap nas.
The best way to recover is to get a Linux machine and install testdisk (mine happens to be Ubuntu 18.04, yes its old), load the drive in an USB external drive, connect the drive to your Linux machine and start testdisk. It found my correct Raid 1 configuration and then I picked my partition with my data on it.
I sucessfully download my 64,000 songs.
Works like a charm. I can now reformat my original disks and reinstall them in my old NAS (repurposed) and then reload them with my now recovered data.
Good luck.

Well, it certainly finds stuff... but many files are damaged and incomplete, which makes me assume that the files were indeed split between the different drives... not sure what to do about that
