Methods and apparatus are provided for suspending communications with a hard disk drive in order to transfer data relating to the hard disk drive between the host and an intermediate communications gateway, thereby isolating the hard disk drive from the bus while this data is transferred. Thus, the driving circuit outputs high driving voltage exceeding the toleration voltage of single transistor. An actuator is coupled to the device or user object and outputs a force on the user manipulatable object or a housing of the device.
