I had to get my mac mini fixed so I took it to a little place called los Feliz Hi-Tech.
A very friendly guy named Brandon took my sick mini and checked it out.
I watched him check it out behind the counter. He even used a stethoscope. I thought that was funny. He told me he was listening to a clicking sound which meant my hard drive was busted.
In the end I lost all my data. But I would recommend going there if you have a mac.
Ask for Brandon. :)
