HD ribbon cable ? I had my HD and CD-ROM connected to the same ribbon cable. I disconnected the CD-ROM from the cable and connected a "slave" HD which was detected. Then I disconnected the "slave" but didn't plug the cable back into my CD-ROM and the computer can't find HD. Plug it in to CD-ROM and it does. I would like to leave the second connection free to add the "slave" temporarily and hook the CD-ROM to the second controller. What do I need to do to accomplish same? And for my info, why does the CD-ROM have to be connected before the system sees the HD?
