Installing internal drives
This section provides information and instructions for installing and removing
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 to enable your
computer to read other types of media. Some of the different drives that are
available for your computer are:
v Serial Advanced Technology Attachment (SATA) hard disk drives
v Parallel ATA hard disk drives
v Optical drives, such as CD drives or DVD drives
v Removable media drives
Note:
These different drives are also referred to as integrated drive electronics
(IDE) drives.
Internal drives are installed in bays. In this book, the bays are referred to as bay 1,
bay 2, and so on.
When you install an internal drive, it is important to note what type and size of
drive that you can install in each bay. Also, it is important to correctly connect the
internal drive cables to the installed drive.
