I bet this is fixed by I tried updating the kernel, bumped to "4.12.5-041205-generic" first but still no dice. @002, @Phil > This feature generally shouldn't be used, because its implementation is > unfinished.

I am currently running "badblocks -v /dev/sde1 > sde1.badsectors.txt" and "badblocks -v /dev/sdf1 > sdf1.badsectors.txt" to see what that comes back with.
