Old HFS partition broken?

[hehe299792458]

I have an older HDD (maybe from around 2014). It's unreadable on my current Mac (M2 MBP running 13.4). But under Ubuntu, I was able to confirm it's formatted as HFS+. It's an 8TB WD Red HDD.



It doesn't mount automatically when I plug it in, and when I try to mount it manually from Disk Utility, it tells me:

Could not mount “disk5s2”. (com.apple.DiskManagement.disenter error -119930868.)


Is there anything I can do to repair / recover this partition?

You should not attempt any repairs right now because often recoverable data is actually destroyed irreversibly that way. How important is that data and what kind of formats are on there, i.e. is it photos, videos, something else?
