ABSTRACT:
In a magnetic disk device that retries to start a motor, a CPU increments an I1 counter if the motor can be started at an initial current value, an I5 counter if the motor can be started in the first trial at a maximum current value, and increments an I5R counter if the motor can be started in the second and subsequent trials at the maximum current value. The CPU adds the counter values to the recording values in recording areas assured on the system area of a disk in monitor value storage processing. Upon reception of a specific command from a host unit, the CPU determines based on the numbers of motor start times in units of start current values recorded in the recording areas whether or not the device is in the risky state, and informs the host unit of the determination result.
