Converting an internal DVD drive for external use is a matter of mounting it into a compatible external shell. The process is much the same as mounting a drive internally, only the electronics for connecting and accessing the drive are located within the external drive shell. Once you are finished, just plug the now external drive into a power outlet, connect it to a PC or laptop via a USB port and you can access any media that the installed DVD drive can read.
