[SOLVED] Desktop Icon needed or not ?

[oxo42]

Hi
  After a new install of O.S. Lite 1.0.8. I have a short cut Icon in the top left of the desktop,
it says 32GB File system.

If I hover mouse pointer over Icon it says  " Removable Volume Not Mounted Yet " if I double click I get  "Authentication is required to mount the device "

The same file system shows up in the Home folder but needs to be mounted to get access.
Do I need to retain this shortcut / or should it not be there.

                                                Thanks.
