A imaging-device driving unit, comprising a signal generator, a detector, and a controller, is provided. The device may be removably secured to a conventional scaffold, providing to power the scaffolding device. A mandrel is positioned within the outer flexible skin, and an expansion mechanism is provided to control expansion of the outer flexible skin to selectively create sealing engagement with a surrounding wall. In another aspect of the invention, one or both surfaces may incorporate a source of dry heat. Therefore, the separation of various fractions may be substantially quick and efficient. Before permitting an initial access to the computer readable data from the mass storage device contents of the mass storage device is verified by executing the instructions contained within the mass storage verification module to generate a set of computed verification data and comparing the set of computed verification data with the mass storage verification data.
