ABSTRACT:
A method, computer program product and hard disk drive for restricting a rate of spin-up/spin-down cycles for a spindle motor in a hard disk drive. The firmware in the hard disk drive determines a maximum rate of spin-up/spin-down cycles the spindle motor is designed to handle over a designated period of time based on the number of spin-up/spin-down cycles the spindle motor is designed to handle over its expected lifetime. The firmware disables the automatic standby mode of operation if a calculated rate of spin-up/spin-down cycles during the designated period of time is greater than the maximum rate of spin-up/spin-down cycles the spindle motor is designed to handle over the designated period of time. By disabling the automatic standby mode of operation, the rate of spin-up/spin-down cycles will be reduced as the spindle motor will not incur a spin-up/spin-down cycle until the automatic standby mode of operation is enabled.
