PROBLEM TO BE SOLVED: To provide "a data processor and a data transfer method" for efficiently executing data transfer between external storage devices. SOLUTION: A buffer with a buffer size which is the positive integral multiple of the least common multiple of the sector size of a transfer source volume and the sector size of a transfer destination volume as a buffer is secured. Then, processing (b1) for reading sectors #1 to #3 for the buffer size from the transfer source file in the buffer, and for writing the data of the buffer in the #11 and #12 of the transfer destination file is repeated until the transfer of the data of the transfer source file to the transfer destination file is completed (b2).
