When I turn logging on, I only get lots of messages from the system drive
and not from any other. So it should work?

When I only have the spindown_time option in hdparm.conf and I do /etc/
init.d/hdparm restart then it tells me: "Setting parameters of disc:
(none)."
But when I add
/dev/sdc {
spindown_time = 1
}
I get "Setting parameters of disc: /dev/sdc."
The output from last reboot of grep sdc /var/log/syslog is

The DPO and FUA things doesn't seem to have anything to do with that?
