ps: speaking of sleeping drives, why do all drive manufacturers make their drives wake up when you query their temperature with SMART? meaning you can set them to sleep when idle (e.g. with hdparm -S) to reduce power usage and temperature, *OR* you can monitor their temperature, but you can't do both. you can use SMART to query some other drive data without waking them up, but not temperature.
i've seen this with WD, Seagate, Hitachi, and Samsung drives. WTF?
I can see that this is a limitation without reason, but what use is reading the temperature of a sleeping drive? It would throw out all your averages. hddtemp will skip the temperature read if the drive is asleep unless you specify the '-w' option. James
