I've still got the docs for the WD chip that would do both ECC and
CRC. When I was securing data for computer forensics, I started with
two interlocked CRCs using different polynomials. Eventually, the
gummint expressed a preference for SHA hashes, so the CRC went the
way of the dodo. SHA was a LOT slower than CRC or even MD5.
