My raid arrays are set to power down after one hour of inactivity, but XP x64 is starting them up occasionally.

I'm not sure but I believe it may have something to do with polling the drive or file checking or something.

Anybody know what it is and how to disable it??

It might be the indexing service. You might be able to monitor this with procmon.
Also it isn't a good idea to allow a raid array to power down if the raid controler doesn't support it and even if it support it, you might wait a lot when trying to access the array after a wake up.
Also some raid controller do periodic check on the drives to verify the raid array, so it might also be this.

allen2 - You were correct, I forgot to to turn off file indexing for that array after adding it to windows disk manager.

All is well.

Powering down an eight drive backup array saves around 45 watts of power.
