Stay away from this disk!

I write this time the same way, what I have already written in Alternate (where I bought the hard drive):
I have this hard drive bought end of August 2009. By the end of January 2010, she ran flawlessly. But after the hard drive has been a permanent clack noise, when I started all sorts of programs. But the worst is that the computer is at the same time to falter, that he goes for a few seconds that then runs again correctly and a few seconds later it starts all over again. That does not stop until when shuts down the computer. So immediately complained. Approximately a month later get a replacement. By mid-September the thing went well. But then again the same story. Guests complained about. Today my spare disk came. I think it's only a matter of time until even adopted the thing. I would welcome the however, because according to 8.5 the Alternate Conditions I would thus make the right purchasing contract rückängig. Never need me again rumschlagen with such a crappy product.

BTW: For Alternate the product has 16 reviews. 6 gave only one point (worst rating). I think everyone knows what that means.
