Clicking noise is bad, it's a hardware issue with the drive. At times a board swap can do the trick, need to check ebay or somewhere for an exact match. May not fix it though, if it does not, you can try a drop of about 3 inches flat on a desk. If that does not work, putting the drive in a freezer for several hours wrapped in a paper towel, then try it. Those at best will get you some time to get the data out, although how much time is unknown. Those things work very rarely.
