I have an Alienware m17xr3. My harddrive has failed S.M.A.R.T tests. Crashing, freezing up. I few times when trying to install windows it did not detect a drive. So here is when it gets interesting. I have 2 bays so I moved the harddrive to bay 2. Run a test and it passed. Installed windows, got it all setup with drivers. Then when I was installing steam, and a few other games explorer stopped responding. Basically required a hard reset. And now windows won't boot. The flag just sits there with its animation. So is my harddrive failing of is it something more serious like a connection? I don't want to buy a harddrive if that's not the problem.
