Reducing a spreading of contaminants within a hard disk drive is described. An adhesive is applied to a first side of a desiccant. Then, the desiccant is utilized to cover a component of a hard disk drive, the component comprising a countersink area surrounding a fastener, wherein said fastener is countersunk within the component. The adhesive is then coupled with the component to encapsulate contaminants lying within the countersink area, thereby reducing a spreading of the contaminants within the hard disk drive.
