File Recovery Of High-Order Clearing First Cluster Based On Fat32

The core technical problems of file recovery are the first cluster number clearing of high-order two bytes and the fragmentation in the file. The algorithm proposed in this paper makes full use of file system information such as FAT, creation time, file identification and fragmentation characteristics, recover easy ones and the files difficult to recover which are recoverable at first, and then analyzes the status of remaining fragments after eliminating many interference of fragments. Experimental results show that the algorithm can significantly reduce the complexity of fragments and improve the accuracy of file recovery.
