My dad keeps telling me that I broke the HDD by overclocking the Graphics Card, is it possible??? (I used NVidia nTune)

No, the gpu can not break a hdd, they use different wires and are not really related. You can get a new hdd for $100 at newegg or Costco. Befor you buy a new one open up your computer and see if the cables connected the the hdd are connected.
