For most drives "sudo hdparm -B 254 /dev/sda" works For some drives "sudo smartctl -o on /dev/sda" is needed before issueing "sudo hdparm -B 254 /dev/sda" For some drives "sudo hdparm -B 255 /dev/sda" might be needed
IMHO it would be nice if hdparm would provide a single command which turns down power management for all drives. see also : https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695/comments/286 https://bugs.launchpad.net/ubuntu/+source/hdparm/+bug/172287/comments/1 http://ubuntuforums.org/showpost.php?p=3909494&postcount=552 http://ubuntuforums.org/showpost.php?p=3672087&postcount=18 -- laptop-mode-tools uses hparm -B 255 instead of 254 https://bugs.launchpad.net/bugs/172282 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
