I have two new IDE CD-ROM drives. One is a CD-RW/DVD ROM and the other is a DVD-RW drive. They are on the same IDE controller and they will both read discs. The problem I am having is that the CD-RW/DVD will burn discs and the DVD-RW will not. Is there something I am missing? Both drives are new after talking with HP tech support they first diagnosed it as a hardware problem. Any help is appreciated.
