ABSTRACT:
A disk drive spoiler for reducing particle accumulation in a hard disk drive is provided. The spoiler includes a body portion for directing airflow generated by a rotating disk, the rotating disk comprising a middle diameter and an outer diameter wherein the body portion directs airflow away from the outer diameter of the disk. The spoiler also includes an end portion for directing airflow away from the middle diameter of the disk towards the outer diameter of the disk wherein the body portion comprises a perforation through the body for reducing suction of particles onto the disk surface.
