Problems solved by technology
[0017] The technical problem to be solved by the present invention is to provide a data protection and restoration method and system based on a hard disk controller, which overcomes the defect of the existing data protection and restoration technology, that is, the program for special control of data protection and restoration may be infected by a virus and lose its function And the hard disk mapping information affects the speed and efficiency of the hard disk because it is stored in the hard disk

Embodiment Construction
[0036] Such as Figure 4 Shown is a schematic diagram of the principle of the present invention. A hard disk controller is set in the computer system, and a hard disk controller BIOS module, a hard disk controller driver module and a protection recovery module are configured for the hard disk controller. After the operating system startup is completed, when the hard disk controller receives the hard disk read and write instructions sent by the computer system bus, it calls the hard disk controller driver module to perform read and write operations on the hard disk, but because the hard disk controller driver module and protection The restoration module is designed in one piece and bundled together. Therefore, all read and write operations on the hard disk will be filtered and protected by the protection and restoration module, that is, the protection and restoration module must perform protection and restoration control on the hard disk data, and the protection and restoration...

The invention discloses a data protection restoration method based on a hard disk controller, which comprises the following steps of : setting the hard disk controller, a hard disk controller BIOS (Basic Input Output System) module, a hard disk controller driving module and a protection restoration module in a computer system; and when the hard disk controller receives a hard disk reading or writing instruction, taking over reading or writing operation on a hard disk by the hard disk controller BIOS module or the hard disk controller driving module and the protection restoration module so as to carry out protection restoration control on hard disk data. Because the invention adopts a design which integrates programs used for special control of data protection restoration with BIOS and drivers of the hard disk controller, the program cannot be removed or avoided by other software (such as virus), thereby the reliable operation on hard disk data protection restoration is realized. The invention also discloses a data protection restoration system and a data protection restoration card based on the method.
Description
technical field [0001] The invention relates to the field of computer data protection and restoration, in particular to the field of computer hard disk data protection and restoration. Background technique [0002] The hardware of a general-purpose computer is mainly composed of CPU, memory, motherboard, hard disk, display, and some peripheral devices. The hard disk is the main medium used by users to install operating systems and store data. To operate the hard disk, the user needs to meet the following two conditions: [0003] In terms of hardware: a hard disk controller is required, and the hard disk controller is generally integrated on the computer motherboard or exists in the form of an external card; [0004] Software: BIOS (Basic Input / Output System) of the hard disk controller and drivers of the hard disk controller under various operating systems are required. [0005] Before the operating system starts (such as the computer power-on self-check stage), the work o...
