I don't mind the automatic filesystem checks occurring every so often, so I never bother configuring the frequency of it. What I found odd was that it decided to make the automatic check occur every 39 mounts for the 1 TB, and 27 mounts for the .5 TB partition.

I assume it is a simple formula, so does anyone know what it is?

From current code it looks like it's some value added to 20 based on the UUID of the partition, if you have
Always good to see the words 'kludgy' and 'hack' in code =)
