This setting (show log to Info) didn't do the trick.
It seemed to me as a likely cause, because I had been trying to get more information (logs) about how my set-up was working.

Do you have more things I could try to find what prevents the NAS/HDD from going into hibernate?

If you have enabled some other kind of disk logging on the NAS that is logging network activity to disk, this might be causing the problem.
