Also known as: checksum error, CRC mismatch
Reported when a computed checksum does not match the stored one, meaning the data is not what was posted. On Usenet the usual causes are a truncated or corrupted article, a segment fetched from a server holding a damaged copy, or disk problems during writing. A client that hits one marks the affected blocks bad and hands the set to PAR2 repair rather than aborting.
