Fig. 2 shows the system module synoptic diagram of hard disc of computer clone method of the present invention; Fig. 3 then shows the operational flowchart of hard disc of computer clone method of the present invention.
As shown in Figure 2, hard disk data copying method of the present invention and system are copied on the son dish 20 in order to one group of data (hereinafter referred to as " raw data ") of will be pre-recorded on the stamper 10.The raw data of being pre-recorded on the stamper 10 for example is aforesaid Windows 98 and Office 97 softwares, and son dish 20 then for example is the Primary Hard Drive on the personal computer.
Hard disk data copying method of the present invention and system comprise two master routines: (1) initial program; And (2) replicon disc program.Initial program is in order to the stamper data are made an image file earlier; And in the replicon disc program, recover the stamper data in the image file again, and write on the son dish.(1) initial program
See figures.1.and.2, initial program comprises following steps: (1-1) the stamper fetch program 311; (1-2) the piecemeal condensing routine 312; And (1-3) image file production process 313.(1-1) the stamper fetch program
At first utilize a stamper read module 110 to carry out a stamper fetch program 11, in order to the hard disk praameter that reads stamper 10 and raw data (data that read out are that 120 square is represented with label); Wherein hard disk praameter comprises the sector sum TOTAL_SECTORS and the partition data PARTITION_INFO of stamper 10.Sector sum TOTAL SECTORS represents that all have stored the sum of the sector of raw data on the stamper 10, promptly represents the total length of the raw data of being stored on the stamper 10; Partition data PARTITION_INFO then represents the subregion situation on the stamper 10.
One that the present invention is different with known technology is characterised in that, the present invention adopts the data copy mode, but not the file copy mode that known technology adopted reads out the raw data on the stamper 10 and be copied on the son dish 20.During the raw data of stamper read module 110 on reading stamper 10, be the sector (used sectors) of only reading data storage, and do not read the sector (unusedsectors) of no datat storage.This practice can be avoided containing useless data in the made image file, and increases the length of image file meaninglessly.For example if the total volume of stamper 10 is 2.5GB, and the total length of the raw data of being stored on it is 1GB, and then image file should only comprise the data of this 1GB.The concrete practice of this step is at first to find out the memory location of each file by the file allocation table FAT of each subregion on the stamper 10, that is store (cluster) number of trooping of each file; Then calculate the sector position that all have stored file data again according to resulting cluster number yardage; Then just the data read of being stored in these sectors is come out again.
From the raw data that stamper 10 reads out, be according to a default block length, be divided into a plurality of blocks (blocks), BLOCK_1 as shown in the figure, BLOCK_2 ..., BLOCK_N.(1-2) piecemeal condensing routine
Then utilize a piecemeal compression module 130 to carry out a piecemeal condensing routine 12, in order to each block data BLOCK_1, the BLOCK_2 that will read out from stamper 10 ..., BLOCK_N does nondestructive compression and handles.
The compression method that is adopted in this step can be any suitable well known compression methods.Generally speaking, the stamper data of 1GB can obtain being approximately the packed data of 0.5GB after general non-destructive compression is handled.(1-3) image file production process
Image file production process 313 is that sector sum TOTAL_SECTORS that program (1-1) is read out and partition data PARTITION_INFO directly deposit the file header (Header) 141 to image file 140 in, and deposits the packed data of program (1-2) gained in to image file 140 packed data district 142.(2) replicon disc program
The replicon disc program comprises following key step: (2-1) son dish supervisory programme 321; (2-2) first comparison program 322; (2-3) second comparison program 323; (2-4) son dish partition programs 3241,3242,3243; (2-5) gunzip 325: and (2-5) write-in program 326.(2-1) son dish supervisory programme
The actual son that carries out coils when duplicating, and at first utilizes a son dish module for reading and writing 210 to carry out a son dish supervisory programme, in order to monitor the total volume of sub-dish 20.(2-2) first comparison program
Then utilize a comparison module 220 to carry out one first comparison program 322, do one relatively in order to the total length of the raw data of will be stored on the total volume of child dish 20 and the stamper 10.
If the total volume of son dish 20 is less than the total length of the raw data of being stored on the stamper 10, the insufficient memory of expression dish 20 then, therefore program will skip to step 3221, end the carrying out of reproducer, and demonstrate the signal that reports an error; Otherwise then program skips to next step 323, carries out second comparison program.(2-3) second comparison program
Son dish partition programs is according to the magnitude relationship of the total volume of the total volume of child dish 20 and stamper 10, and the slightly different practices is arranged respectively.Below suppose: n represents the subregion sum of stamper 10; NS[n] represent the quantity of the raw data of being stored on n the subregion of stamper 10; MS[n] represent the maximum subregion number of sectors of stamper 10; RS0[n] represent not subregion before, the initial preset capacity value of n subregion of son dish 20; RS[n] represent behind subregion the capacity of n subregion of son dish 20.
The comparative result of the total volume of son dish 20 and the total volume of stamper 10 has following three kinds of different situations.(situation-1) is if son dish total volume equals the stamper total volume
If the total volume of son dish 20 equals the total volume of stamper 10, then carry out the first dynamic partition program 3241, it makes subregion according to the former partitioned mode antithetical phrase dish 20 of stamper 10 fully.(situation-2) is if son coils total volume less than the stamper total volume
If the total volume of son dish 20 is then carried out the second dynamic partition program 3242 less than the total volume of stamper 10, its detailed step as shown in Figure 4.(step 411)
At first in step 411, carry out the total volume of following formula: XS=[dish]-[total length of the raw data on the stamper] [total length of the raw data on the stamper]=∑ NS[n wherein] (step 412)
Then in step 412, differentiate whether following inequality is true:
XS＞RS[n]-NS[n]? if then program skips to step 413; Otherwise if not, then program skips to step 414.(step 413)
In step 413, carry out following formula:
XS=XS-(RS[n]-NS[n])；n=n-1
Then skip back to step 412.(step 414)
In step 414, carry out following formula:
RS[n]=RS0[n]+XS
XS=0
Follow termination routine.
For instance, as shown in Figure 5, the total volume of supposing stamper is 1.5, and is divided into 3 subregions, and its size is respectively 400MB, 600MB, 800MB, and the useful data of wherein storage is respectively 100MB, 200MB, 300BM; And the total volume of son dish only is 1GB.
Because the data total length on the stamper is 100MB+200BM+300MB=600MB, it is still less than the total volume of child dish, so the useful data on the stamper still can all duplicate so far on the son dish.
Suppose NS[n], n=1,2,3 represent the length of the data of each section post storage on the stamper, then
NS[1]=100MB+C
NS[2]=200MB
NS[3]=300MB is wherein
C is a default constant, and its value is represented the start-up system program of being stored on the main partition (primary partition) of stamper and the total length of virtual memory data.Calculate for convenient, the preferable practice for example is 100MB or 200MB for the C value is made as whole hundred multiples bigger than the length of these type of data.
Suppose that XS represents the difference of total length between the two of the total volume of son dish and stamper data, then under the situation of C=200MB,
XS=1GB-(NS[1]+NS[2]+NS[3])
=1GB-(300MB+200MB+300MB)
=200MB
Suppose RS[n], n=1, on behalf of son dish, 2,3 utilize the size of each subregion that this dynamic partition method obtains, then in principle
RS[1]≥NS[1]
RS[2]≥NS[2]
RS[3]≥NS[3]
In the preferred embodiment of the present invention, be with remaining storage space XS with reverse apportion design priority allocation to last subregion (also be the 3rd subregion RS[3]).But because the capacity of each subregion has maximum higher limit, thus XS differ all be dispensed to n subregion RS[n surely]; In the case, the surplus of then following XS is dispensed to n-1 subregion RS[n-1]; The rest may be inferred, till XS all distributes.
In last example, suppose that the residual memory space XS=200MB of son dish can all be dispensed to last subregion RS[3], therefore get
RS[1]=300MB
RS[2]=200MB
RS[3]=500MB then just according to this mode antithetical phrase dish 20 make subregion.(situation-3) is if son coils total volume greater than the stamper total volume
If the total volume of son dish 20 is then carried out the 3rd dynamic partition program 3243 greater than the total volume of stamper 10, its detailed step as shown in Figure 4.(step 421)
At first in step 421, carry out following formula:
The total volume of XS=[dish]-[total volume of stamper] (step 422)
Then in step 422, differentiate whether following inequality is true:
XS＞MS[n]-RS[n] if then program skips to step 423; Otherwise if not, then program skips to step 426.(step 423)
In step 423, carry out following formula:
RS[n]=MS[n]
XS=XS-(MS[n]-RS[n])
n=n-1
Then skip back to step 424.(step 424)
Then in step 424, differentiate whether following inequality is true:
N=0？
If then program skips to step 425; Otherwise if not, then program skips back to step 422.(step 425)
In step 425, carry out an error-reporting routine.(step 426)
In step 426, carry out following formula:
RS[n]=RS0[n]+XS
Follow termination routine.(2-5) gunzip
Then utilize a decompression module 230 to carry out a gunzip 325, decompress with the packed data that will be stored in the packed data district 142 in the image file 140.(2-6) write-in program
Utilize son dish module for reading and writing 210 to carry out last write-in program 326 at last again, the decompressed data in order to aforesaid gunzip 325 is exported writes on sub each corresponding subregion that coils on 20 one by one by its former subregion at stamper.This promptly finishes duplicating of son dish 20.
Hard disc of computer clone method of the present invention and system adopt the data copy mode, but not the file copy mode that known technology adopted is copied to the raw data on the stamper on the son dish; Therefore it can be copied to the stamper data on the son dish more quickly than known technology, and in reproduction process, can revise the file allocation table of son dish, to guarantee the security of sub-disc system.Learn by experiment.The raw data of utilizing the present invention to duplicate 1GB, its required time is about 8 minutes and 20 seconds; Relatively known method is required 10 minutes and 26 seconds, and the present invention is obviously more quick than known method.
The above is preferred embodiment of the present invention only, is not in order to limit scope of the present invention; All other do not break away from the equivalence change of being finished under the disclosed spirit or modifies, and all should be included in the scope of following claim.
