Steady vibrations can spell doom for the delicate moving parts inside a hard drive, and for this reason HDD manufacturers employ several technologies aimed at reducing these menacing motions. One such technology involves "Shaping Command Inputs to Minimize Unwanted Dynamics," for which engineering company Convolve holds the patent. The technology can be used to limit vibrations of a hard drive's actuator arm, and according to a recent court complaint, Convolve believes Dell, Western Digital, and Hitachi are all infringing on its patent. Going for the legal hat trick, Convolve is suing for monetary damages, attorney fees, and compensatory damages.
