Digging up an old thread here, I have Drivepool 2.2.0.651 and Scanner 2.5.1.3062, I have 5 drives in an un-duplicated pool and none of the drives ever spin down, I have windows power mangement enabled, I can spin a drive down manually via Scanner but the drive immediately powers back up, windows resource monitor shows no processes accessing the disks. If I stop the Drivepool service the disks stay down,so it suggests its a Drivepool issue, I am also running the Ordered File Placement plugin, what am I missing?
