Abstract
A method for reducing the accumulation of actuator bearing grease in hard disk drives includes periodically forcing the disk drive into multiple unload/load cycles after extended read/write sessions wherein the disk drive has not unloaded. While the disk drive is unloading, the current required to unload the read/write head is monitored. Based on the value of the current, the frequency of the unload/load cycle is adjusted.
