Confirming bug for Samsung NB30 netbook (HD Samsung HM250HI), Precise 12.04 latest, hdparm 9.37-0ubuntu3 does NOT fixes the bug! apm_battery=255 fixed it for me, but there are still a lot of users who can first think their HD is broken and needs to be replaced, as I thought at first. Hardware-killing bug, so much time since this bug was discovered, and no working fix yet :(
Additionnal info about the bug: If netbook is working on battery, even after rebooting and entering BIOS Setup (or booting some HDD utility from flash drive, for example) HD still spins down automatically after a few seconds of inactivity, either netbook is on battery or AC power already. But if I attach my netbook's HD to another machine, HD works fine. I mean what Ubuntu's power management is somehow programmed into hardware (not HDD; BIOS?), and it will spindown HD even when you are not working under Ubuntu 12.04 any more! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/952556 Title: [Precise] [Hardware-killer] HD restarts every few seconds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/hdparm/+bug/952556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
