Abstract


Information and a variety of data in today's information society, the most valuable asset, important data is lost or destroyed will often cause irreparable damage. How to obtain the greatest degree of lost , corrupted data or electronic evidence of a crime , it becomes a problem to be discussed in this paper . This paper focuses on various types of file data recovery and partition recovery complete theory and techniques related to a number of studies , some of the results obtained , mainly summarized as follows : 1. Summarizes the foreign data recovery technology research progress , a brief introduction of the magnetic media storage principle , analyzes the mainstream partition and file system structure . (2) studied the various types of file structure, analyzed various domestic and international data recovery software for files and partition recovery capabilities and their advantages and disadvantages. 3 for traditional data recovery software can not recover the full directory or master file table corruption or loss of data such circumstances is the lack of data flow is given based on the NTFS attributes , pattern matching algorithms, and file-level data recovery incomplete compound document recovery programs , experimental suggesting that these algorithms and programs can effectively recover some data under extreme data disaster . 4 for the traditional partition recovery software can effectively recover corrupted or overwritten several other cases of damaged partition chain , this paper proposes a more complete partition table rules , and gives the rule -based positioning algorithm partitions and partition table entries calculations tools, testing and analysis results show that this method can effectively solve the MBR, EBR and DBR partition recovery after such destruction .
