Clearly this is not some randomized phenomena. Rather bewildering if I do say so myself. There seems to be a pattern of 15-15-30-15-15-30 (minutes) between each cycle. //////////// break, left my computer for an hour or so Here's a list of times that I caught the drive spinning up: The drive spins up at similar times each hour. I did start to notice an interesting trend though. There are no signs of anything in Console within the general vicinity of the times that the drive spins up. Is there a way that I can pinpoint an application or process that is accessing the drive? It's fairly disruptive, and often annoying, to hear the drive spinning up and down every 20 minutes or so. The applications that I have open all the time are: I know that sometimes, when I do "Open File." the drive spins up as it expects that I might be searching for something on the drive, which is certainly understandable. I have set the "Energy Saver" settings to "Put the hard disk(s) to sleep when possible", but when it spins down it shouldn't rewake so soon unless I try to access a file, right?

I also have Time Machine deactivated, so there's nothing there that should be causing this. I know that there are no other computers accessing it remotely, and I don't have any files open which are stored on the drive, so there is really no reason that the external hard drive should be spinning up for access. Every 20 minutes or so, I hear my external hard drive spinning up.
