Yes, because they might not be _completely_ erased - unless they have a 
cleanmarker node at the beginning, then it's possible that they're only 
partly-erased. So it erases them again, just to make sure.

There's no real reason for it to do so - can you get a backtrace (SysRq-T) 
and find out what it's waiting for? That should be fixable.

Yes. The formatting is done specifically to make sure it's safe to power 
cycle at any time.
