Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

[0045] First of all, it needs to be explained that the main storage device for storing information in the computer is the hard disk, but the hard disk cannot be used directly. The hard disk must be divided into hard disk areas one by one. This kind of disk area is called disk partition. In traditional disk management, a hard disk is divided into two types of partitions: primary partition and extended partition. The primary partition is a partition where an operating system can be installed an...

Abstract

The invention discloses a method and device for erasing a disk. The method comprises the following steps: when the current partition of the disk needs erasing, obtaining partition information of the current partition and next partition of the disk; according to the partition information, judging whether the partition superposition exists between the current partition and the next partition; according to the judgment result, determining an erasing operation aiming at the current partition of the disk. By using the method and device provided by the invention, in the process of erasing the disk, the partition information of the disk can be effectively protected so that the data safety of the user is protected.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for erasing a disk. Background technique [0002] With the progress of the times and the popularization of computer applications, people use computer equipment more and more frequently. In daily applications, users often need to save a large amount of data in personal computers, and at the same time, users may often need to delete files containing personal data. However, the general deletion operation that the user does is just to put the file into the recycle bin, then empty the recycle bin, or directly delete the file without putting it into the recycle bin, such as using the shift+delete key combination to delete the file in the Windows operating system. [0003] However, these deletion operations performed by users are mapped to the system level, and the operating system often completes such a series of actions: add a deleted identifier to the file in ...
