Method for protecting hard disk last partition

Abstract

The invention relates to a method for protecting the tail zone of hard disk. Wherein, in the process of starting the computer, first using BIOS to load in one INT13H filter module; then starting the WINDOWS operating system; and loading hard disk filter driving module; with the driving of INT14H module and the hard disk filter driving, the hard disk size feedback to the operating system is equal to the value that actual hard disk reduced by the size of tail zone; the operating system will not actively access the tail zone, but actively stop the read and write operation on the tail zone; the operating system and the application program can not access and modify the tail zone; the hard disk filter driving program can be added into the mounding program when leaving factory and be automatically mounted. The invention also checks the zone list of tail zone before starting the operating system in each computer starts, and automatically builds a main zone lift for the tail zone as TYPE12, with which the new mounted operating system can destroy said zone.

Description

1. Technical Field [0001] The invention relates to a method for protecting a partition at the end of a hard disk, which realizes the protection of data in a specific space at the end of the hard disk. 2. Background technology [0002] Existing brand computers usually provide users with a lot of drivers and applications. In order to save costs, these programs are stored in the last partition of the hard disk when they leave the factory; secondly, brand computers usually provide users with the function of restoring the factory state. , So that users can restore the factory state after the computer is destroyed to reduce the cost of after-sales service. The usual method of the factory state recovery function is to back up the operating system at the end of the hard disk, and then use the recovery program to reinstall the operating system. Since the last partition of the hard disk saves too much important information and data, and ordinary users cannot be allowed to destroy it, it is...

AI Technical Summary

Problems solved by technology

There are two current solutions. One is to make the last partition a hidden partition. The disadvantage of this method is that if the last partition is simply used as a hidden partition, it is easy to be damaged by user misoperation; the other is to use SETMAX Technology, that is, the HPA technology known by some computer manufacturers, mainly uses the SETMAX command specified in the ATA4 standard. The defect of this method is that this technology may cause conflicts with foreign patents.
