Our current HDD has a system ECC function in order to detect and correct DRAM error. 1 symbol error per page (512 byte +ECC) can be corrected by system ECC function, but 2 or more errors per page causes hardware failure. If bad memory locations are registered and never used, the availability and reliability of the system ECC function is improved.
