Abstract: A method for managing a data storage system is provided. The data storage system includes a primary storage device and a spare storage device. The primary storage device includes a plurality of sections. The method first judges whether the primary storage device conforms to a first standard. Once the judging result is NO, the primary storage device is replaced with the spare storage device. The method then scans the primary storage device, checks which sections are failed in the primary storage device, and locates the failed sections. Then, the method repairs the failed sections that can be repaired and judges whether the primary storage device conforms to a second standard. If the primary storage device conforms to the second standard, the method sets the primary storage device as a new spare storage device.
