How to recover data from a failed My Book World edition?

Used some software called “Geeksnerds XFS Recovery”

Now this finds and shows the structure as i used to see it in Windows… and appears all my data is there in the folders as they were…

Problem is, the software costs £129 for the license, so i can recover my files.

The software to try as advised in post 3 doesnt show the XFS partition of where my data is ?
So, given WD make the drive, and the interface, and use that partition format, then a bit more help would be appreciated in recovering my data please…

In essence, the physical drive is OK, and would appear the partitions are intact (although i’m no linux expert!)
The fault is most likely with NAS board itself, or cant read the data partition, etc etc…
