Abstract: 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.

Abstract translation: 通过检查重建/重建表和空间分配表，确定RAID存储系统中的数据重建，通过确定奇偶校验条带是否已被重构，并且奇偶校验条带是否已被分配。 在重建奇偶校验条带之前，检查故障混合驱动器的非易失性存储器以确定其是否可访问，如果是，则将数据复制到新的混合驱动器而不是发生重建。
