Error code HD521-2W after checking hard drive with SMART test
I have HP m9400t desktop, I restarted it by pushing reset button and after that it won't start Windows. It keeps trying loading windows 7 but always goes back to the screen with options "Start Windows normally" and etc. It doesn't load with safe mode either. Then I started PC recovery and after some test it showed me error code HD521-2W. How bad is that? Can I do something to fix it?
