A method for reconstructing a RAID system is disclosed. Plural disks are corresponded to plural pieces of unique recognition data, where each disk corresponds to one of the recognition data. A disk profile is generated according to the recognition data using a RAID system, wherein the disk profile comprises a logic section combined with the disks and the logic section respectively corresponds to the recognition data of different disks based on stored data in different disks. The disks are mounted to a computer device providing the RAID system. The mounted disks are mapped to correct disk mount addresses according to the disk profile to reconstruct the stored data of the disks in the computer device.
