WebAug 12, 2010 · That checksum function actually does both jobs. If you pass it a block of data without a checksum on the end, it will give you the checksum. If you pass it a block with the checksum on the end, it will give you zero for a good checksum, or non-zero if the checksum is bad. This is the simplest approach and will detect most random errors.
