Hermetically-sealed hard disk drive cover perimeter adhesive seal

A method of sealing a hard disk drive (HDD), the method comprising:

• attaching a first cover to an enclosure base having a plurality of sidewalls each having an outermost surface;
• positioning at least a portion of each of a plurality of sidewalls extending from a top portion of a second cover to overlap with at least a portion of a corresponding said sidewall of said base;
• and
• dispensing an adhesive to hermetically seal at least a portion of an inner surface of each said sidewall of said second cover with at least a portion of a corresponding said outermost surface of said sidewall of said base;
• wherein said outermost surface of each said sidewall of said base is substantially vertical, and wherein said inner surface of each said sidewall of said second cover is at an angle from a vertical direction, and wherein said second cover comprises a plurality of preformed corner corrugations and/or a plurality of convex corners with increasing radii in a direction away from said top portion and said base comprises a plurality of corner pockets, said method further comprising:
• bending inward each said sidewall of said second cover such that corner pleats are formed from said corner corrugations and/or said convex corners in said second cover, thereby disposing at least a portion of said corner pleats of said second cover within said corner pockets of said base.
