Bart Samwel thanks for notifying us. Do you think acpi-support should be modified to use "hdparm -B 254" while on AC and "hdparm -B 128" while on battery (including booting from battery)? While on battery you generally want to save power and protect your disk from bumps by parking as soon as possible.
Reducing unnecessary disk activity will prevent some unnecessary unparking while on "hdparm -B 128". Here's some possible disk activity bugs : * the commit interval for the ext3 filesystem should be higher than 5 seconds for laptop users https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/160448 * ext3 partitions should be mounted with noatime or relatime for laptop users https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/160450 * acpid : Log output far too verbose https://bugs.launchpad.net/ubuntu/+source/acpid/+bug/31512 * liferea might cause unnecessary disk activity https://bugs.launchpad.net/ubuntu/+source/liferea/+bug/160460 * thunderbird might cause unnecessary disk activity https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/160466 * tracker : the index delay should be set to a higher value for laptop users https://bugs.launchpad.net/ubuntu/+source/tracker/+bug/160468 firefox might cause unnecessary disk activity when going to a new website https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/160513 hddtemp might cause unnecessary disk activity https://bugs.launchpad.net/ubuntu/+source/hddtemp/+bug/160621 -- 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 the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
