So I just picked up a brand new 27" iMac quad i5 the other day. Yesterday I used migration assistant to move everything over from my mbp to my iMac. It ended up not working out how I thought so I deleted all the info and just moved over what I needed with an external. Now ever since using migration assistant and notice the hdd making a lot of noise no matter what in doing. It's not the fans or anything but it's like the computer is constantly accessing the hdd even when doing simple tasks. Letting transmission run I can hear the hdd being accessed the whole time and it's very annoying. Anyone have any idea what's going on? It was working fine the first day
