wd — Hard disc failure

I am very much impressed with WD products while receiving the feedback's from friends and service from the company side. But my side facing major issues while using the best branded product o f WD. I don't no how, why i am facing these types of abnormalities using a such good product. During the data transfer with my PC it paused many times, but the data transferred after some time or bunch of time. The last time it was paused during the data transfer and automatically ejected from my PC. So i am trying with the another system by using my friend laptops and other PCs, but it was not detected and i lost my data too. So i came to know about the customer complaint portal and the feedback's regarding the action against the complaint. So i raise the complaint and hope to get my backup data and the issue also sort it out. My Device serial number is SR:WX71A98AAS0N.
