Indeed, it looks like he omitted the message that we most wanted to see. Let me repeat here that I find this *very* irritating. It happens, for example, if I try to read a block which is too long. There's no way to know the length of a tape block in advance, so this is relatively easy to get, particularly with DDS-4 drives, and it involves a very slow recovery. Why is this needed?
