Abstract
A power control method for a magnetic disk unit is disclosed. The method includes identifying a type of a last instruction sent to a magnetic disk unit and, in response to identifying the type, setting a wait time that varies according to the type. In response to the wait time having elapsed after a completion of processing ordered by the last instruction, an idle instruction is sent to the magnetic disk unit for placing the magnetic disk unit in an idle state in which power consumption is reduced.
