After using the external drive I noticed its not working properly. for a USB 3.0 drive the data transfer speed was very low. only 1-2 mbps.
when I was backing up my office data I gently picked up the drive to put a clean paper below it as my table was slightly dirty . but I was shocked to see that the internal component of drive stopped revolving and it hanged. I gently shaked the drive and it started again.
I did this again and got the same result.
I placed my palm on external drive and felt that the revolving vibrations( of internal disk) were not constant. there was some tick tick noise in between. I could feel there was some problem. In order to check all your new drives. use this method. If there is any mechanical problem you will definitely feel it
Same thing has happened with me before. on same product( older version wd ultra blue color). I was unlucky. As WD and Amazon both are companies with high reputation and reliability. And this is a one in a thousand chance.
