Hi JF, please upgrade to the latest version of powersaved (0.11.10). It should have entered testing yesterday. In powersaved_0.9.25 the script /usr/lib/powersave/scripts/set_disk_settings used hardcoded device names of the form /dev/hdX in exec_hdparm(). The newer version uses hal for this. Unfortunately I cannot test it with a SATA drive because I don't own one. If powersaved_0.11.10-1 still fails to detect your SATA drive, please execute the commands from /usr/lib/powersave/scripts/set_disk_settings in exec_hdparm() manually. most importantly DISK`hal-find-by-property --key storage.drive_type --string disk` BUS=`hal-get-property --udi $DISK --key storage.bus` ... and tell me, what BUS type you get and also the other output. Thanks, Michael -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
