Your index buckets can hold a max of 215 entries
(because you have 8192-byte blocks), but the
16-bit entry counts look essentially random.

It's possible that you've configured your disk with
overlapping partitions, so that some other program
scribbled over the index thinking it was something else.
cat /dev/sd__/ctl and examine the ranges to make sure this isn't it.

If the partitions are in fact disjoint, then it sounds
like your disk is not healthy.
