I have an external drive via USB connection. I have "lost" the icon from my taskbar which enables safe disconnection of the external drive. I have tried removing and reconnecting the USB cable without any result. Is there a risk of deleting the contents of the external drive if I do not use the "safely disconnect" procedure. ? Please advise me on how to restore the tasbar icon. (My thanks to John from Kansas and others who assisted me in formatting and installing the device when I purchased it about three months ago)
