You could 'back then' too. The program would just fail when it hit the block(s) that were damaged. In the worst cases, that meant at the time that the first block was accessed.
It wasn't a matter of 'K' or no 'K'. It was whether or not data management would provide buffers with records without sending an *ESCAPE message.
