System and method for performing parity checks in disk storage systems
摘要:
A cyclic redundancy check (CRC) system for a storage controller comprises a memory that stores first sector data and a corresponding CRC non-zero seed value. A buffer control module includes a CRC module, calculates a CRC value of the first sector data with the CRC module, and combines the CRC value with the CRC non-zero seed value.
