I figured no one would believe this, so I took a picture of it.
I realized when I got this message (in a fresh Ubuntu installation) that the modular drive I have been using for months, across three or four installations of Crux and Arch, hasn’t been checked in any of that time. That’s my fault of course; I should really have made sure it was being checked, instead of just letting the mount count roll up like that.
Addendum: That’s an ext2 partition, using only the noatime flag. Errors found? None. So don’t let anyone tell you ext2 is somehow more likely to catch an error. I would strongly disagree with that noise. And maybe journalling isn’t as important as you are led to believe.
