Hey guys. I'm in almost the exact same position. Played the screen exchange game; finally got a perfect one and then I've got this annoying hard drive noise anytime there is read access. It's extremely annoying especially when writing in quiet rooms/libraries. I hate this damn computer haha.
Is this a widespread issue on the new models; or are there perfect machines. My 2012 machine is literally silent (like every other SSD computer I've ever owned). This one is noisey as, definitely coming from the SSD.
It really is a non-issue. Solid state electronics can produce noises

Its not defective.
