CD/DVD+RW drive does not recognize any discs (CD,DVD,blank or original). Had just copied a disc and it worked fine, inseted another blank to make a second copy and it says to "insert blank disc", tried several discs and it does not recognize any discs now. Green light on drive flashes a couple times when disc is inserted. Turned off PC and removed side panel, found wire harness going from D drive to E drive (DVD/RW drive) had came unplugged, plugged wire harness back in and restarted computer, but it still would not recognize discs. Updated the driver from Dell website and still does not work???
