I can see my external drives on all the spaces on my MacBook Pro's display, but I cannot see those drives on my external display. Is there a way to make them show up?

The external display is not set as a mirror of the main display but rather as an extension of it. So you can drag the external drive icon (or any file/folder/window) from one display onto the other.

However, this will not 'stick' as when you disconnect the drive and reconnect it, the system will mount the drive icon back onto the primary display (the one with the Dock).

Also, when you disconnect the external display, the system will move any files/folders/icons that were showing on the external display onto the main display.

  • I wish Apple had implemented external displays more consistently. It would be nice to be able to allocate some spaces to the external display. Then the drives would show up and things would work more consistently. In Mavericks the external display is not quite an extension of the main desktop anymore.

  • Right-click on the drives on the main display
  • create an alias
  • move alias icon to second screen

As I've only one screen, I can't verify whether this works in all situations.
