Zusammenfassung:A data storage system includes a plurality of storage devices forming a storage array for storing data and associated error correction codes and a controller coupled to the plurality of storage devices. The controller is configured to, responsive to an error in a data element among the data, rebuild the data element from other data elements and an error correction code in the storage array and overwrite the error correction code with the rebuilt data element.
