I recently ripped an old HDD out of an old Gateway system. I put the hard drive in my PC and tried to format it. Every time I go to format the drive if states that the drive is in use and that it can't format. I have closed nearly every program and background process on my pc to no avail. If anyone can help thanks.
P.S. I am using windows 8.1
