<p>PROBLEM TO BE SOLVED: To provide an information processing system capable of easily executing a write test without securing a special area in an external storage device or preparing a medium dedicated to the test. SOLUTION: In this system, in a controller 20 for controlling the external storage device 30 by being instructed by an information processor 10, a data reading and holding mechanism part 20a reads stored data from the specified area of a data storage area 30a corresponding to the read instruction of a software 10a, holds them in a data storage part 20c, recognizes normality by comparing the held data with the data read out of the same specified area again and then, holds and stores them in the data storage part 20c. A data rewrite mechanism part 20b writes the stored data stored in the data storage part 20c to the same specified area of the data storage area 30a corresponding to the write instruction of the software 10a, recognizes the normality by reading the written data from the same specified area and comparing them with the stored data and thus, rewrites them.</p> |
