The IBM 9332 disk drive uses an absorbent material, strategically located, to prevent water which is condensed following a product shipment in a cold atmosphere from dripping onto the electronics. This moisture, combined with DC power and impurities present on the board, can cause shorts in the electronics. When the IBM 9332 unit is shipped in a cold environment and then moved into a warmer, more moist environment, moisture normally condenses on the actuator housings and drips onto the driver board located beneath them. This moisture can combine with chemicals in the air and on the surface of the board to form a solution which damages the driver board if power is applied before the board completely dries.
