After the new power supply the TC does not connect to hard drive. Have a green light.

Would this apply to the Nuvi 2555LMT?

I have a Macbook 2008 with 10.7.5 on it and am being told that is the end of the line. Will this work on my Macbook?

I am replacing the two hard drives in my 2009 mac mini server. A small copper clip fell of in the process and I am not sure where it was or where it goes back. Its not visible in any of the pictures. Anyone know?
