This invention is a software-based method for facilitating the recovery of a RAID storage system from the simultaneous failure of two or more disks (catastrophic failure). It involves the identification of the logical address and length of the failed areas of the failed disks and the writing of this information into a bad region table which is replicated on each disk. This makes it easier and less expensive to identify the problem areas and make the necessary repairs.
