Bits 15-8 of this word contain the data structure checksum. The data structure checksum is the two's complement of the sum of all byte in words 0 through 254 and the byte consisting of bits 7-0 of word 255. Each byte is added with unsigned arithmetic and overflow is ignored. The sum of all bytes is zero when the checksum is correct. Deskstar 7K500 and Deskstar E7K500 Hard Disk Drive Specification 116
