A kind of hard disk clearing method, system and device

Abstract

The invention discloses a method, system and device for clearing a hard disk. Since the partition information and RAID information of the hard disk are not completely cleared, the subsequent use of the hard disk will be affected, and the incomplete clearing of the data information of the hard disk will not affect the subsequent use of the hard disk. Therefore, this application determines the partition information location, data information location and RAID information location of the hard disk in advance according to the storage information of the hard disk, and then when clearing the hard disk, completely clears the partition information and RAID information of the hard disk according to the partition information location and RAID information location, and Clear some data information according to the data information location. It can be seen that the hard disk clearing method of the present application can not only effectively clear the partition information and RAID information of the hard disk, but also destroy the original data structure of the hard disk to achieve the purpose of clearing data information. High timeliness requirements for hard disk cleanup tasks.

Description

technical field [0001] The invention relates to the field of data security, in particular to a method, system and device for clearing a hard disk. Background technique [0002] As the carrier of data, the hard disk is an indispensable component of server products. At present, most hard disks can be reused, but they will face data security problems. This is because the previously used data is stored on the hard disk. If it is not handled properly, it will cause data leakage. Therefore, for reused hard disks, the data is cleared to important. In the prior art, the hard disk is usually cleared by writing 0s to the entire hard disk. However, this hard disk clearing method takes a long time, especially for large-capacity hard disks, the clearing efficiency is very low, and the high hard disk clearing task cannot be satisfied. Time limit requirements. [0003] Therefore, how to provide a solution to the above technical problem is a problem that those skilled in the art need to ...

At present, most hard disks can support reuse, but they will face data security issues. This is because the previously used data is stored on the hard disk, and if it is not properly handled, it will cause data leakage. important

In the prior art, the method of writing 0 to the hard disk is usually used to clear the hard disk. However, this hard disk clearing method takes a long time, especially for a large-capacity hard disk, the clearing efficiency is very low, and it cannot meet the high requirements of the hard disk clearing task. time limit
