Method and system for quickly erasing files in mass storage devices

Abstract

The invention discloses a method and a system for fast erasing files in a mass storage device. The method includes obtaining information of a target file input by a user, wherein the information of the target file comprises a target file path and a target file name; analyzing the target file path and searching a file system index table of the target file; analyzing the file system index table of the target file, obtaining attributes of the target file and deleting the target file; establishing a false file system index table with a same file attribute structure according to the attributes of the target file; and writing the established false file system index table in a disc. Correspondingly, the invention further provides a system for fast erasing the files in the mass storage device. Through the method, data content in the disc can be fast erased, and through establishment of a large amount of false redundancy files, restoring software is interfered to restore the real target file.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a method and system for quickly erasing files in a large-capacity storage device. Background technique [0002] In the past file storage process, the storage data track of the file storage medium is relatively wide, and the place where the data is written on the track is not necessarily consistent each time, resulting in the fact that the data written later does not completely cover the previously written data. data, and the physical microscopic magnification technology can be used to recover bit by bit the data that seems to be covered but not actually covered. Therefore, many standards for file erasing in the past involved repeated writing, overwriting and erasing, which has achieved the purpose of indiscriminately overwriting data storage tracks. However, in the current increasingly sophisticated storage medium technology advancement, the storage data track has become very narrow,...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a method and system for quickly erasing files of a large-capacity storage device. After deleting data, a large number of false redundant files with the same or similar names and similar sizes are created to interfere with the recovery of files by automatic recovery software, and solve problems. Files that have been repeatedly written and overwritten are easily recovered by automatic recovery software
