摘要:

针对FAT文件系统,目前多数恢复软件难以恢复物理上非连续存储的被彻底删除文件。本文提出一种基于多结构信息的数据恢复算法,结合FAT表中簇分配信息、目录表中起始簇和时间等信息,能够较好地对一些物理非连续的文件进行恢复,提高了数据恢复的成功率。

关键词: 信息安全, 数据恢复, 簇, 文件分配表

Abstract:

The recovery software for FAT file system today cannot recovery the file successfully which stores on nonconsecutive space. In this paper,an algorithm based on multi-structure information of file system is provided,which can recovery the nonconsecutive stored file with high success probability according to the clusters allocation information in FAT and the starting cluster and time data of a file in FDT.

Key words: information security, data recovery, cluster, FAT
