Crc checksums can be wrong if you have multiple bit errors like runs of zeros. (This resets the polynomial computation) http://noahdavids.org/self_published/CRC

Crc checksums can be wrong if you have multiple bit errors like runs of zeros. (This resets the polynomial computation) http://noahdavids.org/self_published/CRC_and_checksum.html http://noahdavids.org/self_published/CRC_and_checksum.html but crc is good to check against single bit errors.
