Abstract
A method and system for are provided for error detection in a mirrored data storage system. The method includes a first mirrored system applying a first error correction code (ECC) algorithm and a second mirrored system applying a second error correction code algorithm. The method reads recovered data in each of the first and second mirrored systems and processes the recovered data in each of the first and second mirrored systems by applying both first and second error correction code algorithms to produce four calculated error correction code values. The method uses the calculated error correction code values to determine the correct recovered data of the first and second mirrored systems.
