Adding a Drive to the System

The internal hard drive and optical drive are standard features of
the notebook. The type of optical drive varies by notebook
model.
An optional drive can be added to the system by connecting it, as
instructed in the drive documentation, to one of the USB
(universal serial bus) connectors or to the 1394 connector. Hard
drive capacity can also be added with a microdrive PC Card. An
SD Card or MMC (multimedia card) can provide additional data
storage.

Using the IDE Drive Light

The IDE (Integrated Drive Electronics) light turns on when the
internal hard drive or optical drive is being accessed.
