Description
Technical field
The present invention relates to the method that a kind of quick copy has protection subregion hard disk; be meant that especially a kind of utilization has copying equipment now; hard disk with protection subregion is duplicated totally, and the hard disk that duplicates is provided with, make the hard disk that duplicates have the protection partitioned method.Belong to computer software and computing mechanism technology for making field.
Background technology
Hard disk as the most frequently used in the computing machine also be most important External memory equipment, be used for storage operating system file, a large amount of user profile and significant data.Therefore, the security of hard disk and reliability are most important for the computer user.At present, a lot of computer makers are divided the usefulness of a blocks of data district as operating system backup and user data backup on hard disc of computer when scheduler.Specific technological means is generally all adopted in this data field that is divided out, makes it to be operated system or the user directly visits by software or hardware technology, can not arbitrarily be deleted.This data field is commonly called the protection subregion.
Before dispatching from the factory, the operating system of installing under the environment of plant intactly can be backuped in the protection subregion.In the user uses a computer process, also can visit this protection subregion by the software of special customization, and, operating system or data can be backuped in the protection subregion, also can be from the protection subregion recovery operation system or data.
Above-mentioned protection subregion generally can be produced by following several method:
1) revises the divisional type sign, make it to become self-defining divisional type, thereby make operating system or common software normally not to visit, play hiding effect.The shortcoming of this mode is to shield identification and the visit of some software with rudimentary formatting hard disk function to the protection subregion.And still may directly destroy described protection subregion by these softwares with rudimentary formatting hard disk function.
2) utilize the hard disk areas defencive function that the new standard (as ATA5 and later hard disk standard) of IDE hard disk supported (as Host Protected Area feature---HPA) create the hard disk protection subregion; the protection subregion that utilizes this technology to realize has good security and reliability; can guarantee that most professional software instruments all can't destroy the protection subregion, also can't see the protection subregion even hard disk is articulated on other computing machines.
The hard disk protection subregion of Chuan Jianing has been realized the safeguard protection to operating system and user data by the way, but has brought trouble when producing to computer maker.Because, adopt special technique and can not be discerned by the copying equipment of specialty by the hard disk protection subregion that said method is created.These professional copying equipment only can criterion of identification fdisk, for example: file allocation table (file allocation table, abbreviation FAT), 32 file allocation table (FAT32), NTFS (NewTechnology Filesystem, be called for short NTFS, be that Microsoft company is a kind of brand-new zoned format of Windows NT operating system design), EXT (Extended FileSystem, the file system of standard in the GNU/Linux system) etc. follow the divisional type of open standard, then can't discern for fdisk through special processing.This causes in the computing machine production run, and the copying equipment of specialty can not be correctly copies to and waits to duplicate in the hard disk being replicated partition information on the hard disk and data.
For first kind of protection divisional type, can adopt the method for overall image copying to be produced, owing to need duplicate all disk tracks, therefore can cause the decrease in efficiency of copying.For the protection subregion that second method (HPA) produces, the security feature of its hardware-level causes the copying equipment of all specialties all can not correctly discern, thereby also can't be correctly according to the image file reflex hard disk to be duplicated that is replicated hard disk.
Because how tame copying service provider has,, just need protect a plurality of copying of the various information notifications service provider of subregion if will protect the form of subregion open simply.Obviously, this neither an effective method, also is unfavorable for safety.And; even disclose the form of protection subregion to copying service provider; copying service provider also needs copying equipment is carried out relevant hardware adjustment or upgrading, can cause the change of copying equipment and the increase of production cost like this, makes troubles for the production of computing machine.
Summary of the invention
Fundamental purpose of the present invention provides the method that a kind of quick copy has protection subregion hard disk, need not consider to protect the type of subregion, just can be fast be replicated hard disk the protection subregion and on data content copy to and a plurality ofly wait to duplicate among the hard disk; Simultaneously, need not copying equipment is done any change and upgrading, can not increase the production cost of computing machine.
The object of the present invention is achieved like this:
What will have the protection subregion is replicated hard disk conversion, it is become can be the common subregion of copying recognition of devices; To be connected to copying equipment through the hard disk that is replicated of conversion, and read the full detail that is replicated in the hard disk by described copying equipment, and copy to and wait to duplicate in the hard disk; Be installed on the computing machine duplicating the hard disk of finishing, and start computing machine; Be arranged on processing module in the computing machine when computer starting, according to the parameter of setting, described common subregion is set to the protection subregion of hard disc of computer.
