Got it! Many thanks for all the help guys!There was a 4.9Gb tar of a system backup that had gone onto the /media/HERA folder instead of onto media/julian/HERA which is my NAS as it was supposed to. I'm going to blame user error for that one.. evidently in my newbieness I set the destination wrongly in the backup application.So Mint wasn't wrong, I was.. predictably. What confused me was Mint's GUI Disk Usage Analyser which seemed to be claiming the problem was with Gandalf - I really need to sort these drive names out! - which is an entirely different partition :)
Glad you found what was the issue!I'm not sure what program you used to generate diskspaceanalyser.jpg but it does seem to show something different than what you'd expect from a program analysing used disk space (especially with du in mind).
The "100%" usage of / in the screenshot appears to show that 100% of disk usage, regardless of a partition, takes place in / or a subdirectory thereof. Which is what / does by definition.
97.7% of this takes place in /media or one of its subdirectories and 98.6% _of that_ in /media/julian.
Indeed, as /usr and /var are in the same partition, it can't be that one is 1.0% full and 0.2% full. Rather, they account for 1.0% and 0.2% respectively of the used disk space in / .
