PURPOSE: To make sure the reproducibility of a fault to be caused only at the time of a certain specified operation or timing, to store fault cases in the past and to effectively utilize them for evaluating a new machine type. CONSTITUTION: At an interface between a magnetic disk device (HDD) 2 and a main body 1 of a personal computer, for example, a bus monitor part 30 is provided to sample interface information to be mutually exchanged and to store that interface information, that sampled information is transformed by a data transforming part 310 so as to be executed by an evaluation test machine 31, this information is executed at the evaluation test machine 31 as an evaluation program and the tests of magnetic disk devices 2 and 2a as evaluating objects are executed. When executing the interface information sampled by the bus monitor part 30 at the evaluation test machine 31, while varying the voltage, temperature and transfer speed to be impressed to the magnetic disk devices 2 and 2a, that information is repeatedly executed. |
