This causes the hdd to spin down every few seconds. But it hardly serves any purpose, as normal disk activity causes it to spin up no sooner than it goes idle. The result is unnecessary load/unload cycles which reduces the life of the hdd. This can be easily overcome by running "sudo hdparm -B 254 /dev/sda" (replace sda with the appropriate disk) manually at boottime. This sets the least aggressive power management. But there is another serious issue. The harddisk is not being turned off properly, it is not spinning down before shutdown. This is leading to an increase of POWER RETRACT COUNT at every shutdown. This problem was there in Feisty and Gutsy, but was absent in Hardy. Now it has again surfaced back in Intrepid. Using the old 2.6.24-21-generic kernel in Intrepid doesn't give this trouble. So I guess this must be a issue with the new kernel. -- Sambit Bikas Pal MS 3rd Year Indian Institute Of Science Education & Research Kolkata, HC 7, Sector-III Salt Lake, Kolkata-700106 Web: http://www.botcyb.org OpenPGP Key: http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x8E57F8B897D372B3 -- Ubuntu-devel-discuss mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
