The checksum is often stored with the data (so if the data is not written or in the wrong location the checksum is still valid) ZFS stores the checksum with the data pointer; so it knows more about the data and whether is was proper. ZFS also checksums before the data travels over the fabric. >... and code is code. Easier to debug is a context sensitive term. Uhm, well, firmware, in production systems?
