In my opinion, the only time when it is really safe and useful for the HD to do -B with less than 254, is when laptop mode is enabled. In Debian I wrote it so that control is left to laptop-mode-tools when laptop mode is enabled and configured, so in those cases the user can configure it differently. In all other cases we cannot be sure that it is safe, so we apply -B 254. --Bart -- 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
