Abstract
A reconstruction method based on a hard disk array comprises determining whether at least one damaged hard disk among a plurality of hard disks of the hard disk array has been replaced by at least one to-be-reconstructed hard disk, and writing a backup data corresponding to the at least one damaged hard disk into the at least one to-be-reconstructed hard disk according to a mapping table and information of the at least one damaged hard disk.
