I have /etc/hdparm.conf
configured to power down the external USB HDD, but it actually never spins down. When I manually turn it off (hdparm -Y
or set its spindown hdparm -S 36
) - everything works as expected.
It seems like my Ubuntu ignores /etc/hdparm.conf
on reboot :( Here's some useful info:
# blkid /dev/sde6: LABEL="BACKUP-HDD" UUID="fee45c66-11bd-49fa-a62a-4a541716e8e1" TYPE="ext2" # ls -lh /dev/disk/by-label lrwxrwxrwx 1 root root 10 2009-10-19 05:59 BACKUP-HDD -> ../../sde6 # cat /var/log/dmesg /var/log/messages | grep hdparm # tail -n 4 /etc/hdparm.conf /dev/disk/by-label/BACKUP-HDD { apm = 20 spindown_time = 36 standby }
Any suggestions how to troubleshoot this?
UPD: launching sudo /lib/udev/hdparm
seems to re-read /etc/hdparm.conf
, but has no effect: HDD is still spinning.
