My Mac froze and i did a force shutdown by holding the power button down.. when i went to reboot it just gets stuck at the loading screen with the apple and the spinning circle on the bottom. I tried resetting my PRAM I tried booting into safe mode I finally tried booting while holding down the option key and then booting from my OSX disk. It gets going up until i need to choose where to install OSX, it says examining disks and it shows my HD but i can't click it. After a few minutes my HD disappears and i can't choose where to install OSX. I'm guessing my harddrive is completely shot? If anyone knows how to fix this, that'd be great...if my harddrive being shot is the case... Does anyone know how much it would cost at an Apple Store to get this fixed? (rough estimate) Also if i purchased a new Harddrive and installed it myself, would this fix the problem?
