Internal drives are devices that your computer uses to read and store data. You can add drives to your computer to increase storage capacity and enable your computer to read other types of media. Internal drives are installed in bays. In this manual, the bays are referred to as bay 1, bay 2, and so on. When installing or replacing an internal drive, it is important to note the type and size of the drive that you can install or replace in each bay and correctly connect the cables to the newly installed drive. Refer to the appropriate section in Chapter 2, "Installing or replacing hardware," on page 13 for instructions on how to install or replace the internal drives for your computer. 10 User Guide
