ABSTRACT:
Rebuilding a storage device after failure of a storage device is disclosed. The method is particularly useful for RAID groups of hard disks. The method may also apply to other storage media arranged as a group. The method includes rebuilding a hard disk in a non-linear fashion according to a heuristic analysis of logical units of the failed hard disk. The method may be implemented in hardware, firmware, software, or a combination thereof.
