Is the drive clicking associated with the drive spinning down? Then maybe investigate the noatime (and maybe nodiratime) mount options.
I had the opposite problem where my drive wouldn't spin down and found out that it was apparently because sync runs every few seconds, which creates a need to write out the last access time of sync. sync was actually always writing out it's own last access time preventing the drive from spinning down. Mounting my partitions with noatime solved that and lets my drives spin down and stay down. It seems that the opposite could be happening here, if the drive is actually spinning down due to agressive power management or low hdparm -S time, then it will have to spin up to write out the last access time of sync. Hope that helps. -- Hard drive spindown should be configurable https://bugs.launchpad.net/bugs/17216 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
