Specs: 2011 27" iMac i7 8GB RAM.... Ok, so I just replaced the internal 1TB with a Seagate 3TB, but it won't initialize the "proper" way.. I get this error: I have to go through the "partition" route... Is this normal for a large drive? And here's another kicker: Shouldn't the fans spin to max cause I replaced the internal drive? This iMac had the GPU replaced via the recall a couple months ago... With that being said, I was experimenting in changing the internal drives before Apple replaced the GPU and the fans revved up... So this is the second time I've opened it up since I've gotten it back.. The first time was to add an SSD.. Anyone else experience this???
