Hi everyone. Is it possible to spin down HDD before it is powered off? My problem/concern is that when I call "shutdown -p now", the HDD is powered off at it's _full_ speed and as a result I hear a noise, which really concerns me. I'm afraid that this kind of shutdown will damage HDD. It's a new HDD, it works fine in Windows, I mean it shuts down w/o this noise. What I need(at least think I do) is to spin down or put into sleep mode HDD right before system will be powered off. I've tried to use atacontrol spindown but sync-ing disks wakes HDD again. I also tried ataidle -s my_dev which puts hdd into sleep mode, but again, same result, when it syncs disks it HDD is waken... Are there any solutions? Thank you in advance.home | help
