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.

Abstract: A disk drive assembly including a spindle motor including a hub and a central axis, at least one disk disk having a central opening positioned on the hub and concentric about the central axis, an annular ring member concentric about the central axis, wherein a first portion of the annular ring member is in contact with an outer surface of a top disk of the disk stack, and a disk clamp ring screw adjacent to and in contact with a second portion of the annular ring member, wherein the disk clamp ring screw provides a clamping force to at least partially compress the annular ring member toward the top disk of the disk stack.
