related topic - leaving SMART control tests ON for a (non-SSD) drive, apparently interferes with sleep; the drive will wake up to test itself. For some drives, I would prefer that not to happen and just stay quiet. Yet, testing for this behavior seems elusive -- querying the disk wakes it, and most linux disk tools seem unaware of sleep state. I just listen for the disk spinning, or notice a long pause before an operation.
