Diagram of hard drive?

Hi! I have a 12gig Quantam Bigfoot TS12.7A hard drive, and it had a head crash. I want to fix it, and have the instructions on how to do so, but the only thing I would like to have before I go putzing around with this is a diagram of what’s where on the inside of the drive. Can anyone point me to one? I tried searching on Google, but no luck there.

Thanx!
