Clicking is probably the worst type of issue to deal with as it's physical. There is a trick that can be tried, but it's a very low chance of working. Freeze the drive for several hours, wrap it in a paper towel to absorb moisture, and if you have one of those packets that absorb moisture you get with shoes and such, place that next to the drive. Then try using it again. The cold will shrink the components and there is a chance that they can shift around enough to function again, even if for a short time.
Other than a full disk recovery by a pro shop I don't think you will get anywhere with the drive.
