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! -- High frequency of load/unload cycles on some hard disks may shorten lifetime https://bugs.launchpad.net/bugs/59695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
