Connecting the Cables
Once your optical drive is in its bay and secure, all you need to do is to make sure it has powerand that your computer knows how to communicate with it. This is done with two different SATA cables: power and data.
1) Connecting the SATA power cable
The SATA power cable is an obviously wired cable that comes from your power supply and ends in a thin, black plug. Just plug that into the appropriate place on the back of your optical drive.
2) Connecting the SATA data cable
The SATA data cable is a thin cable terminating on both ends in an L-shaped connector that probably came with either your drive and/or your motherboard. Plug one end into a free SATA port on your motherboard, and the other end into the port on the back of the drive.
