"safely remove hardware" icon is in my tray at start up even when I don't have hardware in. It ways it's for USB Mass Storage Device for 4 drives which I think are my memory card slots. Also when I use a hardware and then safely remove it out, then put a hardware in again, my pc doesn't know it's there and the safely remove hardware doesn't pop up. In this case I have to restart up my pc again. I've been to device manager and there's an "!" on it but it says it's working properly. Please help me.
