  • ECC system for generating a CRC syndrome over randomized data in a computer storage device
    Patent number: 6052815
    Abstract: An error correction processor is disclosed for correcting errors in randomized data read from a disk storage medium, where the randomized data comprises ECC redundancy symbols generated over the randomized data and check symbols generated over data before being randomized. The error correction processor comprises an ECC decoder for correcting errors in the randomized data using the ECC redundancy symbols; a syndrome generator, responsive to the randomized data, for generating a validation syndrome; a correction validator for comparing the validation syndrome to a predetermined value to verify the validity and completeness of the corrections to the randomized data; and a derandomizer for derandomizing the randomized data after the correction validator indicates that corrections to the randomized data are valid and complete.
