When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board. Some CD/DVD drives
may also have an audio connector; one end of the audio cable will attach to the drive connector and the other will attach to the system board.
Connect hard drives to data connectors labeled "SATA" and connect CD/DVD drives to connectors labeled "IDE".
