When I'm on my MacBook Pro, I have two 1TB drives connected to it. 2x Iomega Ultramax 1TB -> both through FireWire 800 One for media storage. One for time machine back-ups. Now ... sometimes when I load the finder or have to choose a location to save my file in an application (doesn't matter which one) ... I can hear one of the drives (presumably the media storage one, right?) spinning up until it reaches its full speed and after that the finder loads. So, to me, it sounds like the speed of my machine is being held back by the speed of the external drive ... is there a reason for this? And more important a solution? Does my machine need to index the external drive before being able to show folders in the Finder? And if so, doesn't OS X automatically index the connected drives at start-up? Thanks in advance !
