hi, when you plug-in your ACER CDRW go to BIOS setup make sure its detected.. if its detected at windows go to device manager..check for any problem.. you would see a question mark.. if the drive got problem..
same thing with your external dvdrw when you plug-in to your usb, check your device manager..if its recognized or working properly.. or try to plug-in to another pc check whether your external dvdrw is working or not..
post back..if still cannot..
