XFS - astronomical file sizes

[resonator79]

I recently bought R-Studio 9 for Windows (having been a user on macOS way back when), trying to undelete a few files from Unraid XFS drives;
I did the usual, scan, analyzing, finding the files - however, unlike with NTFS and HFS+, some of the files have astronomical file sizes, and are not recoverable - see screenshot

The deletion happened during a SyncThing mishap, and the data has very likely not been overwritten, since I pretty much immediately (within minutes) shutdown the server and went at it, yet R-Studio says "below average".

Is there any chance of getting back these files? Am I missing a feature of R-Studio maybe?

Thank you.

Looks like the file system is severely damaged. Cannot say more without deep inspection of the file system.
I'll try to find our what may cause such damages.
Right-click the files and select Get Info on the context menu. This information may give some more clues.

Thank you.

Side note - there's another file I'm looking for on another drive of the Unraid array; same properties, 2EB size. I somehwat doubt that both those drives have "severely corrupted" filesystems, as they've been running inside the array for over a year, and there weren't any problems.

For some reasons the first sectors are damaged. Did you scan disks for Known File Types? This may help.
It's really hard to give advice without thorough inspection of the file system.

I rescanned the drive, making sure all video formats were selected. Same outcome.
Would it help to upload the scan file somewhere so you can take a look at it?

I will ask our profs.

Can I raise a proper support ticket maybe?
