Dear list, I am trying to achieve the HDD _simple_ power saving function on Open-RD Client device, running Linux 2.6.22 / 2.6.36.
The simplification is that I just need to spin the disk down and then sit quietly waiting for IC2 port expander's IRQ (button press) to reboot the system. Is the `sg_stat --stop' command from sg3_utils package capable of performing the disk spin down for SATA device (WD) on this armish platform? If not, please direct me to proper solution. Is it feasible running full power saving mode (i.e. using spindown daemon [1]) to be able to wake the hard disk and resume normal system operation? Thank you in advance, Pawel.
