Cable Select. If it works, the master will be on port 0 and the slave on port 1 of the controller.
I have a Plextor 708A DVD drive and a newly received Plextor 760A DVD drive. I cannot get the computer to recognize both on the same cable. I set the 760A as the master and the 708A as the slave. I am using Windows XP on an Asus P5W DH Deluxe motherboard. No matter what combination I tried, the computer would only recognize one drive and not both. Each drive worked perfectly when on the cable by itself.
Before going any further, I think I might have figured it out but wanted additional opinions. After pulling my hair out and trying almost every combination possible, with Plextors tech support,I think the problem might be my cable. I read in the 708 manual that it uses a 40 pin cable. I read in the 760A manual that it uses only an 80 pin cable. I believe I have both hooked up with a 40 pin cable (as the connectors are not blue, gray and black). Could this cause one drive to intermitently not be recognized? I say intermitent because every once in a while, the computer would recognize both drives but rarely.
