I am trying to install a cdrw on the same cable with the cdrom. Currently on the cable that I am trying to install it I have cdrom and it is the master so the cdrw is the slave. But the computer is not recognizing the cdrw and now it is not even recognizign the cdrom either. The device manager says that the cdrom is installed but when you open the icon of my computer the cdrom icon will not show. Thank you for the help.
