Apparatus and method for determining motor spin direction of a hard disk drive

摘要

A method for determining motor spin direction of a hard disk drive is provided. The method includes forming an air inlet on a first sidewall of a disk drive base. The method further includes forming an air outlet on a second sidewall of the disk drive base wherein the air outlet comprises an airflow indicator coupled to the air outlet for indicating whether air is moving in or out of the air outlet. The method further includes rotating a disk drive motor inside the disk drive and determining the motor spin direction of the disk drive motor based on whether the air is moving in or out of the air outlet.
