In my computer was an 80 wire cable used for the hdd, but for the dvd and cd drives was a 40 wire cable used. It's not certain that your computer already has a 80 wire cable, but it's easily visible, probably printed on the side of the cable too. The connectors are (at least with my cable) blue (mobo side), grey (slave) and black (master). While they are capable of transferring much more data (to ata 133), you better check it. It could solve some problems, however, it's never certain. Good luck!
