Connecting the External SATA device
The E-SATA Connector allows you to connect an
external Serial ATA device. Users can now utilize
shielded cable outside the notebook to take
advantage of the benefits the SATA interface brings
to storage.
The E-SATA standard interface supports
"plug-and-play" technology, so that you can
connect and remove the E-SATA devices without
turning off the notebook.
To connect the E-SATA device, simply connect the
cable of the device to the E-SATA Connector of
your notebook.
