Abstract

Disclosed is a method for recovering damaged data from a hard disk having damaged data which comprises the steps of reading the hard disk drive and detecting sector information; analyzing information on the file allocation table (FAT), root directory, and data sectors from the detected sector information, and searching damaged directory information; using a searcher interface and recovering the found directory; displaying sector viewers of the data and directories; checking, through the displayed sector viewer, and determining whether or not the clusters are fragmented; when the clusters are found to be fragmented, manually dragging and dropping an FAT editor, and automatically editing allocation values of the respective clusters so as to recover the data, and storing the recovered FAT information in a storage device; when the clusters are found not to be fragmented and after the recovered FAT information is stored, storing the recovered data in another drive; checking whether the stored data have been recovered normally; when the stored data has been recovered normally, marking the allocated FAT as the cluster used at the time of recovering the data; and when the stored data have been abnormally recovered, manually editing the allocation values of the clusters.
