I have Dell Latitude C640 with Western Digital 40GB. The harddisk is 3 days old (brand new) and I have 900 load cycle count. My harddisk "clicks" (increases load cycle count) roughly twice a minute (regardless battery or AC mode), but (this is important) only when there is absolutely no other harddisk activity. If I use some app which few times a minute reads or writes a file, there is no load cycle count increase.
I have also tried Windows XP - there is no cycle count increase, no hdd clicking. In BIOS, hdd clicks once (the sound is distinguishable from normal activity) - after that, it's silent. In Ubuntu 7.10, twice a minute. For those who have IBM/Hitachi, you can try download Hitachi Feature Tool http://www.hitachigst.com/hdd/support/download.htm and disable/tweak APM manually right from that livecd. Maybe after that you will not have to hack scripts (maybe it can "force" the APM setting), but I am not sure of that. -- default value in power.sh potentially kills laptop disks 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
