I can't see usb-drives and archives in the sidebar of the finder anymore [duplicate]
Solution 1:
In your Finder sidebar, can you see your internal hard drive listed under Devices? If you hover over Devices you should see either Show or Hide just to the right of it, perhaps it's set to hidden?
Solution 2:
In my case it was a faulty usb drive. I still don't see the hard drive in "Finder" sidebar, but I'm figuring that's just the way it is with Lion? I adjusted the Finder Preferences so I can now see the HD and other drives on my desktop...
