O), and proceed to step S1006.

In step S1006, the buffer counter value is determined according to the size of the intermediate file, that is, it is determined whether all the data of the intermediate file has been processed. If all processing has been performed (YES in step S1006), the flow advances to step S1009. On the other hand, if all the processing has not been performed (NO in step S1006), the process proceeds to step S1007.

In step S1007, the area 12 in FIG.
The copy destination LBA set to 03 is advanced by the block size of the read buffer. Here, FIG.
If there is no copy destination LBA set in the area 1203 of the read buffer for the block size of the read buffer, 0 is set. In step S1008, area 1 in FIG.
The buffer counter set in 204 is decremented by one, and the process returns to step S1012.

The steps S1003 to S1
The data flow up to 008 is specifically shown in FIG. In FIG. 15, reference numeral 1504 denotes a copy destination disk. The data of the intermediate file 1503 is read by the number of blocks in the read buffer, and is sequentially written from the last LBA of the copy destination disk 1504.

Returning to the description of FIG.

Step S1005 and Step S100
If it is determined in step 6 that the processing has been completed to the beginning of the disk area of the copy destination disk or that the reading of the intermediate file has been completed, the process advances to step S1009 to close the intermediate file and delete the file. Step S101
