Extremely slow WD Elements external hard drive

Hello,
I have also problem with HD WD Elements. It is extremely slow. I tried to pull my data out, but after 10 hours I pulled only 800MB…
I tried also scan disk with WD DLG Tool. Quick scan taked 11 hours and didn’t find anything.
Extended scat is running already 7 hours, and estimated time remaining is almost 9000 hours.
Please help, I don;t know, what to do, how pull data and how repair disk.
Thank You
