Hi all, I've followed instructions from a couple of YouTube videos (including the OWC one) on how to replace the existing hard drive with an SSD. The existing 5400rpm hard drive seems to seat differently that on the instructions and videos. It is seated deep down and will not come off. I can't even reach it with my fingers to try and lift it up. Is there something I'm not doing correctly or has Apple changed the design? If so, do I need to remove the logic board perhaps to make more room? Thank you!
