NOTE: You do not need to install the device security screw unless you want to prevent the optical drive from being easily removed.
Your Dell computer ships with a CD/DVD drive installed in the optical drive bay along with an M2.5 x 8-mm device security screw. If the security screw is not already installed, it will be packaged separately. When you insert a drive into the bay, you can install the device security screw to prevent the drive from being easily removed.
Removing the Optical Drive
CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: To prevent damage to optical drives and other devices, store them in a safe, dry place when they are not installed in the computer. Avoid pressing down on them or placing heavy objects on top of them.
