I have had a few false "disk not ejected properly" messages pop up on a laptop. By false, I mean that no device of that name was ever attached by me. The device name was a person's name (not mine, etc.) in one case and a normal-sounding attached storage device name in another (also nothing to do with me). No device was attached at any time proximate to the messages. This feels very uncomfortable. What's up? Thoughts? Ideas?
