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. Your computer comes with the following factory-installed drives:

•An optical drive in bay 1

•A 3.5-inch hard disk drive in bay 3

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 “Installing or replacing hardware” on page 121 for instructions on how to install or replace internal drives for your computer.

Figure 53 “Drive bay locations” on page 120 shows the locations of the drive bays.

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts.

When you handle computer parts and components, take these precautions to avoid static-electricity damage:

• Limit your movement. Movement can cause static electricity to build up around you.
