What all is in Sporlight's Pref Pane's Privacy tab?
I could *almost* see it spinning up my startup drive (if I hadn't already does a search and if TextEdit and/or OSX 10.4 was written by idiots)
I doubt you want to engage the tards that wrote any later OS then, IMHO, 10.4.11 was the apex for OSX... went downhill ever after.
Spotlight's Privacy tab has my 12GB hard drive so that isn't indexed, but not my startup drive.
This is driving me crazy. It's obscene. It just spun up both hard drives a few min ago for no reason whatsoever which is why i am finally back here posting again.
I am running OSX 10.4.11 and frankly I don't hear my drives change their spinning. It may have something to do with your preferences settings or other software you run. Anyway, while not spinning the drives saves energy I thought it was best to keep drives spinning because it's the starting and stopping that's hard on them. I have some drives in my G4 that are at least 8 years old and have been spinning all the time since I usually leave my computer on 24/7 unless I am away overnight.
You'll have to find somebody whose idea of a fun time is running Terminal and watching system processes come and go to see what's triggering this.
How old are these drives? Don't some newer "green" drives have their own energy saving featues built in that may control rotation?

It's hard to figure out i/o activity with disks. How much effort do you want to put into this?
I seem to recall the information for what files not to search is divided among your disks. So, when you do a Spotlight search, each of your disks will be accessed.

I have run across terminal commands to set sleep time.
