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 -- hdparm's feedback about -B values is misleading https://bugs.launchpad.net/bugs/172287 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
