I finally fixed on my laptop (Acer Aspire 1662, Kubuntu Gutsy 7.10 - HD Hitachi Travelstar 60 GB) by editing the file:
/etc/hdparm.conf with: /dev/hda { apm = 255 spindown_time = 255 } No more parking at all and non problems of over-heating. My girlfriend's laptop (Toshiba A100, Kubuntu Gutsy 7.10 and HD Toshiba 120 GB) reached about 26000 cycles in about 110 hours of use. The option below (apm=255) seemed not to do anything. I tried apm = 254 and it stopped clicking at all but the operating temperature of HD was increased dramatically. So I choosed a value of apm = 210 which caused a good compromise between parking and over-heating. I hope my personal experience could be useful... -- 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
