I use hdparm and hddtemp:

The script with which you reply is missing the sleep 60 loop.

The problem with cron is that I get those cron logs I do not like,
and
that the update time of 60 seconds is a little long. Running the
script in
a loop, started in .kde4/Autostart, would be better, but as a user
I have
no permission to call hdparm or hdtemp. I do not want to be part of
the
disk group, and when using sudo I would get the logs by sudo I
wanted to
avoid. So now I SUID'ed hdparm and hddtemp, changed the group to
wheel and
disabled execution for others. cron problem not solved, but
workarounded.
Running a script which contains `while true ... sleep 60` will cause
only a single logging action. You can run it as root at startup
using /etc/conf.d/local.start and have the file world readable.
Sorry, this wasn't very clear:
If your script contains `while true ... sleep 60` then you'll only
need to run it once.
