The recovered error should prompt a request sense by the host. That
request sense should report the address of a bad block. It should NOT
simply report the first block of the packet containing the recovered
error. In the case of multiple recovered blocks in the same packet, I
would prefer to see the address of the first recovered error. However,
seeing only the last error from the packet is FAR better than seeing the
first block of the packet which contains the bad block (when that block
did not actually cause the recovered error).
