Embodiment

For being well understood to purpose of the present invention, feature and effect more, now by following specific embodiment, and cooperate appended accompanying drawing, the present invention is illustrated in detail, illustrate as the back:

The method 30 that the multiple master of making IDE hard disk of the present invention is cut apart, please cooperate referring to Fig. 1 and show the hard drive space map of IDE hard disk according to the inventive method made, its main function is that the IDE hard disk is divided into two

zones

10,20, the first area of being cut apart 10 is to adopt the partitioning scheme that meets existing cut section standard, for example adopt and meet the IBM personal computer standard fully, therefore can make concessions and use existing operating system, the Windows of Microsoft for example, (SuSE) Linux OS etc., the platform of being developed comes normal errorless access, in order to allow for the purpose of disclosure of the present invention is easy to understand, the concrete example of first area 10 is to adopt to meet the IBM personal computer standard fully.Therefore the second area of being cut apart 20 is to allow above-mentioned platform come access owing to be fully incompatible in the IBM personal computer standard.Method 30 of the present invention is owing to take specific partitioning scheme to second area 20, so can be according to the demand of practical application, second area 20 is divided into the main cut section 201 of not limitting quantity, has so overcome the shortcoming of traditional partitioning scheme of IBM personal computer standard fully.

Fig. 2 shows the process flow diagram of the inventive method.Method 30 of the present invention includes step 301, step 303 and step 305, is respectively described below.Step 301 is that the IDE hard disk is divided into first cut zone 10 and second cut zone 20, wherein first cut zone 10 is to adopt the partitioning scheme that meets existing cut section standard, that is the segmentation result that is presented in first cut zone 10, just general just like the FDISK instruction of carrying out traditional dos operating system, or just like the execution result of above-mentioned PartitionMagic software.

Step 303 is the main cut sections 201 that second cut zone 20 are divided into again at least more than one.Implement the mode of this step, it is the technological means that to utilize about main start record (MBR), predetermined space in second cut zone 20, special storage is in order to cooperate second cut zone, 20 employed main start record 201A, and main start record 201A is used for defining main cut section 201, for example defines the reference position and the end position of each main cut section 201.Because traditional partitioning scheme of main start record 201A and IBM personal computer standard is incompatible, therefore also just can't do access to each main cut section 201 of second cut zone 20 in the application software of traditional work platform.

Step 305 of the present invention is with hiding second cut zone 20, to prevent that second cut zone 20 is carried out the access of unauthorized.Though the application software of the traditional work platform under normal the execution be can't access to second cut zone 20, yet therefore the present invention is stashed second cut zone 20 in order to guarantee the safety of second cut zone 20.The means that step 305 adopted, can utilize the instruction SetMax decided at the higher level but not officially announced of ATA (AT Attachment-ATA interface) to instruct reaches, by carrying out the read-write that the SetMax instruction just can limit the IDE hard disk, it is confined within first cut zone 10, according to and prevent from second cut zone 20 is carried out the access of unauthorized.
