Yes, you need a new HDD, preferably solid-state. I’m going through the exact same thing and the best thing to do is take out the bad HDD and '''leave it alone''' until you can clone it to an HDD of the same or bigger size. Chances are, the new HDD will inherit the corruption, but a database rebuild should do the trick, although you may lose some data in the process. Make sure to back up all your data beforehand, if you can.
