A disk drive includes a disk drive base and at least one rotatable disk including a disk surface extending to an outer disk edge. The disk drive further includes a head stack assembly rotatably attached to the disk drive base in operable communication with the disk, the head stack assembly including an actuator arm disposed adjacent the disk surface. The disk drive further includes an airflow blocker coupled to the disk drive base for mitigation of disk rotation induced airflow upon the head stack assembly. The airflow blocker includes a blocker body disposed adjacent the outer disk edge attached to the disk drive base. The airflow blocker further includes a blocker arm portion extending from the blocker body along the disk surface. The airflow blocker further includes a planar portion extending from the blocker arm portion disposed along the actuator arm when the actuator arm is rotated over the disk surface.
