We tend to > assume that there was some reason for that... the reason is not always reasonable. Maybe the BIOS programmer assumed a specially tuned distribution which never materialised. Maybe some manufacturer wanted to impress with better runtimes on battery and did not care if the harddisk is broken after 2 years. Whatever the reason, many users think it is better to change the setting - is there any reason why the power manager should not make it really easy? I did read that various a few drives have a special interpretation of the numeric values but I do not see a problem if the sysadmin chooses the value and have never heard of any serious saftey problems.
