Problems solved by technology

However, the indirect layer will also generate copy data that is invisible to the user. Based on this, the traditional methods of shredding and deleting files, overwriting, and low-level formatting the drive cannot ensure the complete deletion of SSD data.
[0004] In the prior art, the data on the SSD hard disk is usually completely cleaned by erasing the entire disk. Erasing the entire disk of the hard disk will also delete all the system data, resulting in the need to reinstall the operating system, which is very troublesome.

Abstract

The invention discloses a hard disk data cleaning method, device and computing equipment. The method is executed in the computing equipment, comprising the steps of: acquiring equipment information of each hard disk in the computing equipment; determining whether each hard disk can be cleaned according to the equipment information, to determine one or more hard disks that can be cleaned; display the device information of one or more hard disks that can be cleaned, and obtain the target hard disk selected by the user; and randomly write data to each partition of the target hard disk until the remaining space of the target hard disk is The space is smaller than one data block, so as to trigger the garbage collection mechanism to perform data cleaning on the target hard disk. According to the technical solution of the present invention, it can realize the thorough cleaning of the SSD hard disk data on the basis of retaining the original files of the system.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a hard disk data cleaning method, a hard disk data cleaning device and computing equipment. Background technique [0002] At present, the penetration rate of SSD solid-state drives continues to grow, and the speed and capacity continue to increase, making SSDs gradually replace mechanical hard drives. The storage principle of SSD is different from that of mechanical hard disk, and the method of data destruction is also different from that of mechanical hard disk. [0003] SSD solid-state hard disk has its own master control, which converts the storage of physical data through the indirect layer between the logical block address of the operating system to access data and the address of the original data flash memory, and manages the writing of each data block by hiding the special interface of the flash memory entry and erase times. This indirect layer enhances the access perf...
