When searching for a file with OS 10.4, hitting "command F" brought up a search window with a menu bar across the top with buttons reading "Servers," "Computer," "Home," and "Others" that enabled one to search in specific places. If one clicked on "Others," a window named "New Search" opened up with an "add" button that would allow you to navigate to any folder or subfolder in order to narrow the search even further or to choose an external hard drive if the file you needed was there. Snow Leopard gives no choices other than to search "This Mac" or the user's account. There's no "Other" function that allows me to direct my search anywhere else, not even to my external backup drive! Is this an "improvement?" What am I missing? How can I search for files on my external backup drive?
