Beside the intended way, I did actually find another use-case for MAX LBA.   I do buy broken HDDs which only have relocated sectors and no real issues. Then I do 5 full formatting runs to check if the number stays stable in a 48h stress test.   But one of 3 Disks was actually broken. During the first run, I did discover the place where the sectors get relocated by monitoring the formatting progress and monitoring at which point in time new sector relocations did happen.
