Oh, that answers one question. In the case of truly damaged media, every
drive behaves differently... cdparanoia does not yet deal gracefully with
quite a few.

*This* is a known cdparanoia bug. The error is spurious.

A definitive explanation on '!':
Cdparanoia verified the same section of data twice and got two apparently
perfect segments, but when compared to each other, one is different from the
other, and that was the first indication that cdparanoia had of trouble.
At that point, it makes an educated guess.
