btw, i had already disabled idle spindown with hdparm -S 0
On the WD Green disks, all the smartctl APM-related commands are NOOPs. You can disable the spindown, or set it to a certain amount, but your drive wouldn't obey that at all. (That was my experience of fiddling with those settings, anyway)
idle3-tools just updates the firmware settings so that it's disabled by default (as should be the recommend setting for WD Green drives on any linux system)..
Not quite, see above. Am curious if you actually managed to adjust stuff -- were those all "green" branded disks? Which models? (Just wondering if WD has relented and let the OS adjust things now)
I had experimented with spindown over summer (didn't want my drives to overheat) but found that ZFS didn't like it. at all. kept getting drives being booted from the zpool seemingly at random, so ended up disabling it. of much less importance, I also found that hddtemp woke the drives up anyway, whenever it queried the temperature.

It's a Debian package since yesterday evening.
