Abstract:
A hard disk drive determines whether the hard disk drive is powered by a battery. This determination is used to select an operating RPM value for the hard disk drive. The fly height of a slider on a hard disk drive can be tested at a low operating RPM value. If the fly height is acceptable, the low operating RPM value is enabled to be selectable for the disk drive. In addition to a low operating RPM value, a high operating RPM value can also be selectable.
