"I have a WD 1TB hard drive that is fairly good."
it would seem this is not the case. you can make no assumptions about drives as to their "goodness" This is a cosmetic mistake, but not relevant to your issue.
1st question: Did you follow the advice of windows and do the format, or even attempt it?
There are a number of reasons why this could have happened, and really we cannot help more without more information. is this drive USB2.0 or 3? What is the model and have you tried a different cable? Have you tried using a booster power USB cable?
Does it make any strange/unusual/different than new noises? can you notice an black or burnt parts on the circuit board (if you have cracked open the case)
If your data is important, You would be best to take it to someone experienced. You can start at your local computer shop, and stress that they not do anything without your permission, such as taking the cover off to have a look or other horror stories in-the-making.
sorry, it is a can of worms, and youve opened it.
