Locating internal drives
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 drive installed. Refer to the appropriate section in Chapter 2,
“Installing or replacing hardware,” on page 15 for instructions on how to install or
replace internal drives for your computer.
