To enhance the reliability of equipment by preventing sudden machine down by measuring a transfer time of a hard disk, detecting a sign of the failure of the hard disk based on the measured transfer time, and displaying the warning of the failure or avoiding the use of the failure portion.
The image forming apparatus having the hard disk includes: a reading part to read data from a plurality of data areas of the hard disk for each data area; a measuring part to measure the data transfer time for each of the data areas when reading the data by the reading part; a comparison part to compare a first data transfer time measured by the measuring part with a second data transfer time measured by the measuring part; a determination part to determine whether it is predicted that the failure will occur in the hard disk based on the comparison result; and a processing part to perform predetermined processing corresponding to the occurrence of the failure when the prediction of the failure occurrence in the hard disk is determined.
