Problem: I have a folder which I deleted from my external hard drive. Whenever I empty Trash, I get the insufficient privileges error. The folder is empty. I've tried emptying the trash, securely emptying the trash and used these Unix commands in Terminal too: rm -rf .Trashes rm -rf [directory] sudo rm -rf [directory] rmdir [directory] And all these return 'Operation not Permitted'. The file is actually in the Trash and only appears when I plug in my external hard drive. I get the 'Insufficient Privileges' error when I empty trash from the Finder. How do I get rid of this bloody folder?!
