    Abstract: Method and apparatus for securing a disc stack to a spindle motor hub. In some embodiments, a disc clamp assembly includes a spring clamp with an annular contact portion which contactingly engages a disc stack and a central aperture through which a hub projection of the spindle motor hub extends. A plurality of interlocking semi-annular shim segments interlock together to form a continuous retention ring assembly which wedges between the spring clamp and a shoulder surface of the spindle motor hub.

    Abstract: A hard disk drive comprises a sensor configured to detect a mixing ratio within the hard disk drive and a membrane electrode assembly. The membrane electrode assembly comprises a gas flow path that couples an inside of the hard disk drive to an outside of the hard disk drive, and the gas flow path includes a cathode and anode that electrolytically remove water vapor from the inside of the hard disk drive. The drive further includes an energy source coupled to the membrane electrode assembly and a controller coupled to the sensor and the energy source. The controller is configured to activate the energy source in response to the sensor detecting a mixing ratio greater than a threshold mixing ratio and to deactivate the energy source in response to the sensor detecting a mixing ratio less than the threshold mixing ratio.
