Jeremy has addressed the NCQ issue, about which I know nothing. As for APM and AAM, that functionality is handled by sysutils/ataidle, which that PR appears - on a quick glance - to pretty well duplicate. I see phk@ recently added an 'atacontrol spindown' command to HEAD and RELENG_7 that appears to offer similar functionality to 'ataidle -S standby_mins' or 'ataidle -I idle_mins', though specified in seconds instead. However this doesn't address acoustic management. Or is ataidle broken for SATA disks? cheers, Ian
