Internal HDD Damaged or Cable?

So the other day my macbook pro late 2012 took a bad fall from my kitchen counter to the hardwood floor. Since then I have not been able to boot up my macbook. It stops at the grey screen with the apple logo and the spinning gear. I've tried to erase the internal hard drive but during it gets stuck about half way and i get an error that says " Disk Erase failed with the error: File system formatter Failed". Now when i check the status of the hard drive it says that it is infact verified so do i need to get another hard drive or do i need to get a new cable to connect it with?
