Zusammenfassung:Data reconstruction in a RAID storage system, by determining if a parity stripe has been reconstructed and if the parity stripe has been allocated, by the checking of a reconstruction/rebuild table and a space allocation table. Before reconstruction of a parity stripe occurs, the non-volatile memory of a failed hybrid drive is checked to determine if it is accessible and if so the data is copied to the new hybrid drive instead of reconstruction occurring.
