Study Basing On The Disc Partition Data Restores Technology

With the development and application of information technology, the computer is been widely used in many fields, such as national economy and military affairs. As the main facility of data storage and data exchange in the computer, the high capacity and high density discis keep a great deal of important resources and imformation. In practice, some objective factors, for instance, misoperation, accident, virus-infection and destroy, lead to the chaos of disc partition information, thereby, lead to the lost of important data and eventually bring about unremedy loss.The hard disk as the carrier of data and information, requires that the reliability and the endurance for the data protection certainlly. the data's values on the hard disk are sometimes more important than the hard disk itself surely. It is extraordinary important that how to recover the important data when the data disaster has appeared because of those unexpected situation.The data recovery of the hard disk is to mostly recovery and restore from the damaged memory or operation system.the limits for restoration objectively, mainly depended on the limit for the data damage, on the preparation for date security and on the operation after the data damage.so ti is the problem for data restoration that to keep up with data security, to reduce the changce of data disas. The special restoration is the best choice for those people when the data disaster appeared.The paper analyzes the partition table and the organization relation, discovers its corresponding value relations and the inherent laws, according to the different disk partition structure, the different file systems. First, aims at the logical lock breakdown, designed the restorative algorithm, and combines the security pass, designes the data protection algorithm. second, aims at the loss for partition table damage, summarizes the existing restorative algorithm, designs the complete backup algorithm and the manu-caculation algorithm to avoid or reduce the data disaster for partition destroy. third, aims at the data disaste for the misoperation, designed and realized one kind based on the protected algorithm basing on the disk privilege area, protected the important data, and accessed the data in the privilege area by password. Finally, the paper simply elaborated the data ultimate restoration, and discussed the certainty and the related method basing on the protection for data security.
