My hard drive won't spin down even it's idle for a while.
When I put my iMac into sleep, the hard drive will spin up every 15 - 30 mins and then goes back to sleep.

I keep getting this message in Console while the mac was sleeping. Are they the cause of this problem?

Thanks!

HDD from some manufactures does not sleep after a while if it is being disconnected from computer. Turning off computer would cause HDD stop spinning in moments. I think this is due to HDD firmware and controller not able to let disk spinning down and turning off entirely.
I have bought a lot of WD My Passport HDD and all could auto spin down after disconnecting from computer.

But you say your HDD spins up every 15 -30 min and goes back to sleep. Then I think this might relate to Mac OS X. I don't know more detail about this though.
