Unless I'm missing something, if you click the arrow to the left of Questo PC, it should expand and show them all there.

Yes of course and thank, but i ask if its possible have the disks showed without click on This Computer every time i want see a different disk

The only other way I can think, is if you right click on each of the drives, it offers the option to add to Quick Access (or Accesso Rapido), then they will appear in the list at the top left?
