Drives and dmg's mounting okay but not appearing in the Finder sidebar Drives and dmg's are mounting okay on my Mac, and I can find them at /Volumes/. However, they aren't appearing in the sidebar in the Finder. What's the best way to start fixing this?
In Finder you can show or hide the disks and other devices

Go to the sidebar and mouse over DEVICES you get to the right text that says Show or Hide. Click on that word to toggle the display of the devices.
