Hello folks, I have a Seagate Blackarmor NAS that was used for backing up old files in our company.
We had three 4TB Seagate hard drives that have been configured as a span, and one of them died (the last one). I've tried to recover the volume by replacing the disk and accessing the NAS configuration page, but it failed. Now I'm trying to recover the data from the other two disks, but I don't have much knowledge in data recovery, so I'm trying to learn how can I do it.

I've scanned the first drive on the Wodershare RecoverIt software, and it can read the data, but the filenames are messed up. Searching about this, I've found that it's because the directory info could not be found. Is there a way to recover this info?
In ReclaiMe File Recovery, it shows some info about the drive and the span: https://prntscr.com/truw5n

Can you help me with some tips on how to recover this data with the original filenames, if it's possible?

SPAN(JOBD, Composite volume) - Cannot be saved by replacing the disc. Only do the recovery of the failed disk.

Can you show us the Partitions windows in DMDE? That should normally only take a minute or less, no need for a full scan.

Thank you for answering fzabkar. Here's the partition info you asked: https://prnt.sc/tta3yw

This was the first disk on the SPAN, by the way.

What did the second disk show?

We need to find the first and last sectors of each 4TB segment of the DATAVOLUME and then stitch them together. Then you will at least recover every file that exists within the first 8TB of the 12TB volume.
