A method is disclosed for making improved, cleaner computer devices by using a cleaner pressure sensitive adhesive (PSA) on the computer device components that contain a PSA. The cleaner PSA comprises at least one hydrogenated styrene-elastomer-styrene block copolymer or the hydrogenated styrene-elastomer-styrene-elastomer block copolymer, and at least one tackifying resin. Hydrogenated styrene-ethylene butylene-styrene or styrene-ethylene propylene-styrene block polymers in combination with certain "clean" tackifying resins are formulated into a liquid coating, coated and properly dried on an acceptable substrate. The component thus produced is ideally suited to be used in disk drives. The component produced in the manner described, has a much lower total aggregate concentration of materials considered harmful by the industry, compared to most polyacrylate adhesive components of the same design. Also disclosed are computer devices, preferably computer data storage devices, made by the method disclosed.
