Re: query tape media block size

I'm not sure if tape is re-labeled; it might use existing bs from header or the one in device properties.  Chances are that is more feasible that it reads current setting on device, but you can test it.  To see which bs you have, you can use scanner command.  Having it set to bigger one is not an issue; imagine setting for bs to be your mouth while actual bs is egg. Obviously, egg smaller than your mouth will pass through - other way around I'm afraid it won't.
