Design method of multi-hard disc sub-time destroying

Abstract

The invention particularly relates to a design method of multi-hard disc sub-time destroying. According to the design method of multi-hard disc sub-time destroying, destroyable hard discs, a destroying circuit, an external controller and a power supply are arranged, wherein the power supply is used for supplying power for the hard disc and the external controller at the same time; the external controller is connected with the destroyable hard discs through the destroying circuit; and through the external controller, hard disc destroying signals are output at different times, so that the sub-time physical destroying of the hard discs is realized. According to the design method of multi-hard disc sub-time destroying,, the safe privacy of stored data and the power consumption problem of the physical destroying of stored mediums are comprehensively considered, so that the condition that destroying is carried out twice at the same time is avoided, continuous, safe and reliable power supply can be ensured in the hard disc destroying process, the low-power consumption physical destroying of multi-hard disc storage equipment is realized, and a feasible conference design is provided for the physical destroying of the large-capacity storage equipment.

Description

technical field [0001] The invention relates to the technical field of destroying computer hard disks, and specifically relates to a design method for time-sharing destruction of multiple hard disks, aimed at hard disks with physical destruction functions that are relatively common in the market. Background technique [0002] Destroying confidential information is an important part of maintaining information security. The key to achieving confidentiality is how to ensure the safety and thoroughness of destruction. Generally speaking, to ensure the safe and complete destruction of information, physical destruction and software destruction should be started. [0003] Physical destruction refers to starting from the storage medium and destroying the hard disk by physically damaging the storage medium; software destruction mainly refers to repeatedly reading, writing and erasing through software programs to make the data in the original storage space unrecognizable , so as to a...

Problems solved by technology

However, usually the power consumption required to physically destroy a 512G hard disk can reach 35W~50W. For some storage devices with multiple hard disks, this destruction method is undoubtedly a great burden on the power supply.

[0006] Considering the security and confidentiality of stored data and the power consumption of hard disks in the process of physical destruction, in order to avoid the problem of excessive power consumption in the process of simultaneous destruction of hard disks, the present invention proposes a time-sharing destruction of multiple hard disks. design method
