Can you run that WD tool so we can get a better idea of that drive's health? When you run it it'll also report SMART status, but you can click on that status and it'll open a window that'll show all the SMART attributes and their current values. Post screenshots of that if you can.
In the case of a failing hard drive, where it's not known how much longer it'll last, there's a decision to be made: try and grab data first or try to make a clone first. Depends on how critical that data is and how much access time you think you've got left for that drive. You also have to wonder if you'll even be able to get a working image/clone from it.
Here's a link to an iso that you can burn to a CD/DVD or write to a flash drive that'll boot a version of Macrium: Macrium WinPE
Macrium can be used to create an image of your drive which can be written to another drive. Info on use here: Imaging with free Macrium
