Query: Great until it breaks

So I got the lifedrive for Christmas and it was great until it froze a few weeks later. I tried rebooting, turning on and off, everything but nothing worked. It was very frustrating. I've been reading lots of reviews that describe the same thing so be warned. It was a great device until it froze then it was just a waste of money.
