I am trying to install a second hard drive in my desktop. the cable inside the computer to hook up the hard drives has two ends, "master"(black end) and "slave"(grey end). the cable has labels designating which is master and slave. the hard drive already installed is hooked up using the "slave"(grey) connector, and the "master"(black) end is free. obviously my second hard drive will only be used for storage, so it will be the slave drive. i don't assume the connector end matters, but i wanted to be sure. thanks.
