[Bug 816388] hdd goes to sleep too often - maybe damages disk
http://bugzilla.opensuse.org/show_bug.cgi?id=816388 --- Comment #60 from kolA flash <kolAflash@kolAhilft.de> --- Created attachment 615483 --> http://bugzilla.opensuse.org/attachment.cgi?id=615483&action=edit hdparm related files from kubuntu-14.04.1-desktop-amd64 More information: Tested with an openSUSE 13.2 x86_64 KDE live-image on my notebook (from USB memory) on ac-power. Started "hdparm -B /dev/sda" after booting. Result: 128 Tested kubuntu-14.04.1-desktop-amd64.iso on my notebook (from USB memory) Started "hdparm -B /dev/sda" after booting. Result: 254 Looks like these files (extracted from the Kubuntu system) are the reason, why Kubuntu has a value of 254. (attached a copy of these files in the provided zip file) /etc/hdparm.conf /lib/hdparm/hdparm-functions /usr/lib/grub/i386-pc/hdparm.mod /usr/lib/pm-utils/power.d/95hdparm-apm I propose openSUSE should do it the same way! (maybe we have to do it via systemd instead of power.d) Nevertheless, the Kubuntu file "95hdparm-apm" says "On battery we set hdparm -B 128". I think also on battery openSUSE should use a value of at least 192 or higher! Every 2.5 inch hdd I have, has dramatically increasing loads/unloads for values smaller than 192. Spending a little more power is less worse then breaking peoples hdd's!!! -- You are receiving this mail because: You are on the CC list for the bug.
