Query: Unreliable& undependable backup drive

Number of reviews have been written about the problems with this drive. my addition;Drive and configration is unreliable, as a backup drive, it is not dependable. I bought two, one failed out of the box, the other is margional. If the drive failes to connect through USB to the system as disk drive, the software backes up the information on the C drive. Assume your C drive fails, backup you thought you bought is non existant. The reliability of the configration is many times worse then internal hard drive, and it has a questional backup software.I tried to get Western digital to help, I would have been glad to pay additionl money to understand the problem and have this beautifully packaged drive to work. No such ideas were forth comming. Enough, enough?????????????.
