<P>PROBLEM TO BE SOLVED: To execute a scan of a disk even when a command is always issued at prescribed intervals. <P>SOLUTION: In this storage device 100, a BMS (Background Medium Scan) execution part 193 compares an expectation progress rate and a progress rate of a progress rate management table 181 in each forced BMS monitoring time (X), decides whether or not the progress rate is the expectation progress rate or above, and forcibly executes a BMS between the commands outputted from an upper device until the progress rate becomes the expectation progress rate or above at a period of a periodic monitoring time (Y) without waiting an idle time (a state that command reception from the upper device is absent) when the progress rate is less than the expectation progress rate. <P>COPYRIGHT: (C)2008,JPO&INPIT |
