It is pretty clear that there is some type of single-bit corruption
with your disk:

001000

Note that all of the "02000200" bits are set for most of the superblock.
I'd suspect either something bad in the controller or maybe a cable.  If
this is present throughout the disk then there is nothing that can be
done about it, except restore from backup.
