Another thing about computing world is that not everything is logical,
you don't have to deal with bits and bytes only, but also with
people.  Many operating systems start counting disks with 1.

You could argue other operating systems do other things and you will
be right.  But a decision has to be taken, which is what Okuji did.

It has nothing to do with floors, but it does have something to do
with counting.  No one starts counting with 0.  Except when you count
partitions, of course. ;-)
