Problems solved by technology

[0006] Although this hard disk chip protection method can completely prevent the hard disk from being copied, there are still some disadvantages in this protection method. First, it will increase the hardware cost; second, the hard disk capacity and specifications of each electronic device are different. It is difficult to copy a large number of copies during production; third, there is no way to save the data in case of a real problem

Embodiment Construction

[0023] The file system is the basis for the operating system to access files in the disk. Any data file system stored on the disk will have records, and the operating system uses these records to achieve the purpose of file access.

[0024] Referring to Figure 1, user 1 issues a read or write command to operating system 2. The operating system 2 searches the file system 3 according to the command from user 1 and the file name of the target data 4, and executes the command when the target is found. .

[0025] After a general electronic device such as a desktop computer (hereinafter referred to as a computer) is turned on and the POWER On Self Test (POST) is completed, an instruction (INT 19) is called, and the instruction sets the 0th magnetic column ( Cylinder), the 0th side (Head), and the first sector (Sector) are loaded to the hard disk, and this sector loaded is the master boot record of the disk, and then the command transfers the control of the system to the master boot reco...

Abstract

The invention relates to a hard disk copy resistance method. The harddisk copy resistance method provided by the invention includes the following steps: firstly a starting up program is executed by a storage unit of the hard disk; secondly, a main starting up record is written back to the hard disk; thirdly, an archiving system of the hard disk is driven according to the record information of the main starting up record; fourthly, the main starting up record memorized by the hard disk is erased. The invention overcomes the technical problem that how to prevent the hard disk from stealing and copying in the protection mechanism of digitizing contents in background technology, lowers the hard disk protecting cost, leads the hard disk copy resistance to be beneficial to copy largely when in batch process, and improves the reliability of hard disk copy resistance.

Description

Technical field [0001] The invention relates to a hard disk copy protection method, in particular to a hard disk copy protection method that writes a master boot record (MBR) into the hard disk when an electronic device is turned on, and erases the master boot record (MBR) after the boot is completed. Background technique [0002] In recent years, the development of hard disk technology has advanced by leaps and bounds, and the capacity of hard disks currently on the market has exploded to tens of GBs, or even hundreds of GBs, in a short period of time. Faced with such a large memory space, how to achieve full use and effective management will gradually be valued. Due to the advancement of hard disk technology and market competition, the hard disks available on the market today are not only large in capacity, but also economical and affordable in terms of price. Therefore, the storage unit cost of hard disks is greatly reduced. [0003] For example, as far as the core components ...
