I get this pop-up every 15min or so. "Windows No Disk" in the error box is the message "There is no disk in the Drive, Please insert a disk into the drive" No drive letter is specified. I've tried putting disks in every drive, & still get the message. I have to hit the "cancel" or "continue" key several hundred times to get the scan to complete. I cleaned the registries using a commercial program, but this annoying message is still there. Does anyone know how to get rid of it?
