Dear all
I am experiencing the same issue of many of you: I bought a Mac Book Pro at the end of June 2012. In late september it started to make abothering constant noise, coming from the right front corner. I brought the machine twice to Apple care service. Once they replaced the fan; nothing changes. I returned, they said this time the noise is not originated by the fan but by the hard-drive. They confirmed 2012 Mac Book Pro models are more noisy than previous models, but stiil this level of noise is not acceptebe as an issue by Apple.
I then contacted Apple directly and opened a claim; finally, they are offering me to change the hard-drive of my Mac. Now I have an Hitachi, which brand should be less noisy? If I followed correctly the previous post, it's not really an issue of brand, but of luck. Toshiba sometimes is better other times makes the same noise..
I'm also wonder if it can't be even worse, as so far I did not experienced the regular click noise, maybe it could start with a different hard drive!
I'm very very disappointed with the product, I can't believe that Aplle can develop products that are more noisy than previous ones.
Thanks for any advice on the issue
