A hard disk drive with a head, and a disk that is rotated by a spindle motor. The drive includes a controller that operates in a low-speed idle mode where the spindle motor speed is reduced and the head is moved to a contact start-stop zone of the disk. Reducing the speed of the spindle motor, instead of spinning down the disk allows the disk drive to rapidly resume normal operation. Parking the head at a certain area of the disk, instead of a position off disk, allows the drive to more readily re-establish a mode where data can be retrieved or stored.
