i had an issue of when my pc loaded up it would read that it couldnt find the operating system, tryed with partitions and clean install but still no luck so i decided to just do a destructive test using pc check 6.5. low and behold one of my hard drives failed. i installed windows 7 and everything runs fine appart from the errors i have attached via picture but the harddrive seems usless at this point. am i safe to remove it without causing more harm to my pc and am i right in thinking the errors are related to the hard drive
