Under OSX my iMac would sleep after a few minutes of inactivity - the video and drive would shutdown/spindown. How can I make it do this under YDL? I tried hdparam, but it won't accept an APM command.. # /sbin/hdparm -B 50 /dev/hda /dev/hda: setting Advanced Power Management level to 0x32 (50) HDIO_DRIVE_CMD failed: Input/output error Thanks, Brian
