Abstract
A system for maintaining cyclic redundancy check ('CRC') protection of XOR'ed data sectors includes a register that is initialized with a non-zero seed value used for generating sector CRC values. The system includes logic for combining CRC values of at least two sectors and storing a result of the combination modified with a non-zero seeded CRC value.
