"Does black hole have an internal state, that depends on the states of all the particles that fell into it? If so, the emanating radiation can be computed from that internal state, so information is preserved." If I understand, the short answer from Stephen Hawking is "no." The only properties they have is mass, angular momentum, and charge.
