Embodiment Construction

[0022] For the convenience of operators, it is recommended to use third-party software for this method:

[0023] Hard disk cylinder or sector modification tool FTOOL, hard disk partition tool PQmagic, sector read and write tool diskrw, ISA module compilation tool romos.

[0024] Take the 160G hard disk as an example.

[0025] 1) Use FTOOL to modify the capacity of the hard disk

[0026] First start the pure DOS environment, it is recommended to use MS-DOS7 or above, and enter "ftool" in C:\> (or use a floppy disk to boot and A:\>) to run the Hitachi Feature Tool software, and select the "IAgree" approval agreement Afterwards, the software will scan all hard disk channels of the host computer and give information about all identifiable hard disks. Use the up and down cursor control keys on the keyboard to select the hard disk that needs to be protected.

[0027] After selecting the hard disk to be modified, press the ALT+F key combination, and use the up and down cursor contr...

Abstract

The invention provides a data storing method capable of protecting hard disc from clearing or low level, belonging to the field of restoring data of a hard disc protection region. The method comprises the following steps: A, modifying the number of cylinders or sectors of a hard disc; B, dividing the hard disc into three main partitions once again, and using up whole volume of the hard disc; C, restoring the original number of cylinders or sectors of the hard disc, and partitioning the rest volume of the hard disc by the main partition mode; D, storing important information in the fourth main partition; and E, backing up the partition table information of the fourth partition, and forming the partition information and an automatic recovery program into a standard isa module which can be identified by a basic input / output system (BIOS), modifying and adding bios into the isa module, and refreshing the modified bios. The method provided by the method can store data permanently, and prevent low-level formatting or clearing.

Description

technical field [0001] The invention relates to the field of recovering data in a protected area of ​​a hard disk, in particular to a data preservation method capable of preventing the hard disk from being cleared or low format. Background technique [0002] The hard disk capacity of personal computer is getting bigger and bigger now, and the hard disk of more than 2TB capacity has appeared in personal computer at present, and the multimedia data of hard disk storage is also more and more because of the diversity of personal digital products. However, once the hard disk is damaged by viruses or caused by logic locks and needs to be low-formatted or cleared, the user's data will no longer exist, which will cause great losses to the user. Although the recovery software has a certain ability to restore data, it is time-consuming and laborious, and it is difficult to ensure complete retention. It has almost no ability to restore hard disks that have been cleared or low-formatted...
