Comment 477 for bug 59695

Oh my god, it's so stupid. It turned out that my issue was hddtemp running in daemon mode. Because it uses smart (sic!) to query drive temperature, and update interval is hard-coded to 60 seconds, it was waking my drive every 60 seconds! As soon as I disabled it, my problems seem to go away. The drive spinned down and doesn't wake up for several minutes already, just like it should. =^_^=

So for the rest of you, check that you don't have anything checking smart in the background, hddtemp in particular...

P.S. On the side note I find it crazy that to check drive temperature you need to spinup... x_x ...I couldn't even suspect that!
