to gagarine : * because currently the reasoning goes that manufacturers should set appropriate settings (because they should know what their hardware is capable of) * because applying an apm of 254 might cause the harddrive's temperature too increase too much for some harddisks * because it isn't trivial to find the right power management settings. An apm of 192 is different for each harddisk. * because it is not only power management which causes this issue. It's a combination of disk access and power management. * because this workaround also uses 254 also when running on battery. When running on battery the disk you don't want to disable parking of the head to protect the harddisk. I based the ugly fix I recommend *only* for heavily affected users who understand what they are doing on this workaround and other comments : http://ubuntuforums.org/showpost.php?p=3675960
I think this bug should get a higher priority. IMHO wishlist is too low.
