MAC can not find the hard drive WD my book studio 2tb

My MAC can not find the hard drive WD my book studio 2tb, when I go to disk utility, it says that the void content in jurnalen.Jag bought new hard drive, copied contents to the new disk. The problem persists. When the entire disk contents are copied to the new disk, follow the problem. There is a journalfel in Your WD drive is also copied to the new disk. With it, you can not access the copy on the new disk, either. So you have two versions of your faulty disk content. The new drive can not get up on the desktop because the error followed.

I have very impotent information, dokumentary film, I must save it!

Can you help me, please!!!

Hello, you can try using another USB cable to connect the My Book, or connecting the My Book to another Mac to see if the same problem happens.
