I have my DVD Rom on my secondary controller cable as the master and a CD burner as the slave. However, it is listed as "E" drive for the dvd rom and "D" for the cd burner. After installing the software that came with the DVD rom it reconize's only the cd burner and not the dvd rom. Also, after manually adjusting the dvd software to reflect on the dvd rom, I can not play any dvd movies. Help!
