In the pdf on http://www.seagate.com/staticfiles/support/disc/manuals/desktop/Barracuda%20LP/100564361a.pdf you can read that APM is not supported on the disk. Now I'm confused. I can set APM on at least one of my drives. How can I prohibit the excessive loading/unloading of the heads if APM not is supported? I have set the spindown time do 1h with hdparm -S242 on all these drives. / Fredrik Tuomas -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
