Has anyone succeeded in spinning down disks under Fedora?
I've done the following and the "hdparm -C" does show the disk spun down, but the next time I look it is spun up, and it stays up. The disk is unmounted and I've stopped and disabled smartd, so it isn't accessing the disks. I don't think anything else is either. I'm probably missing a trick somewhere, but what???
disk=/dev/sdc
hdparm -S 120 $disk hdparm -y $disk hdparm -C $disk
