How to Unmount the Drive
Option 1: From the Desktop:
One at a time, drag the Drive's CD PART and HD PART icons to
the Trash. After both icons disappear from the Desktop you can
safely turn off and/or disconnect the Drive.
Option 2: From within the Finder:
Locate the CD PART and HD PART icons in the Sidebar. For
each icon click the eject symbol (the triangle with the bar
underneath). After both icons disappear you can safely turn off
and/or disconnect the Drive.
