I've been finding Finder slow on my brand new Retina MacBook Pro.
I've got two external disks connected to my Mac most of the time. One is a Time Machine backup, the other is a Clone, also for backup. They spin down when not in use which is great. However, I've noticed that Finder is slow to respond. When I access Finder, I hear them spin up and then it is responsive.
Is there anything I can do about this?
