Summary: I hit my laptop because I got real angry. I guess I shook the hard drive so bad that my Windows 8 computer was done with. I bought this and put it in. I tried to put windows 8 back on. Some HP propriatory stuff would not let me do it with this hard drive.
Summary: This is the same model HDD that came in my Lenovo V570. I've run it almost daily for four years and it's still going strong. I never abuse my computers, but I don't just surf the net and check emails either.
