Abstract
A disk drive includes a disk drive housing having a breather hole and a separate leak testing hole, both the breather hole and the leak testing hole being formed through the disk drive housing, and a drive sub-component attached to a surface of the disk drive housing so as to form an interface between the sub-component and the surface of the housing. The interface defines an interface outer perimeter and a sealed airflow testing channel in fluid communication only with the leak testing hole to enable a non-destructive detection of leaks at the interface. The airflow testing channel may be disposed within the interface outer perimeter.
