I unplug the external reader/ writer when not in use.
Sorry, there was a problem. Please try again later.The drive may get its power from the PC USB power. I do not believe it has to remain connected. If you prefer for it to have continuous power, you will to connect to the USB Y type cable, which is not supplied.
