As far as I can tell by default Ubuntu does nothing to alter the hard drives default power management setting during the boot up phase. So you get the default set by the BIOS or the hard drive manufacturer.
This will cause failures because some disks default to a setting of 128, and that means they wear out by constantly parking their heads. There are a load of bugs popping up on launchpad about this problem. I'm going to duplicate them to this one and make this master. -- 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
