I have a Plexwriter 40/12/40A CD-Rewriter. The problem I am having is the green light constantly flashes when closed and my PC will not start up until I open the CD-rewriter drawer. I cannot use my cd-rewriter as it has to stay open for the PC to function. The green light is constantly flashing when opened and closed. Does anyone know why this is happening and how I can stop this because I am unable to use my CD-Rewriter?
