Its caught errors before that probably avoided people losing data. Its a good
sanity check. The "stupid" defaults are two other things

        o Using 1K blocks on large disks (4K is way faster) and
                4K checks way faster too

        o Not using the "sparse superblock" option on large disks
                when creating them.

Unfortunately I dont think there are any "in place" fixers for those creation
time choices
