Early 2011 MacBook Pro 13inch Hard Drive Noises
I have an early 2011 MacBook Pro 13" using OSX version 10.10.5. with a 2.3 GHz Intel Core i5 processor and 4GB memory. Overall, it's been a great machine! However, I notice some clicking noises (almost like if you were dropping a ping pong ball on a table) coming from the right side of the trackpad. I'm assuming that this is my hard drive. Is this noise normal and I just never really noticed it before, or is it a sign that I should start looking at buying a new machine?
