hdparm installs an init script with a /etc/conf.d/hdparm file which |
| 28 |
allows you to set things up at whatever run level you are using. Also |
| 29 |
beware things like "laptopmode" which take over rewriting the kernel and |
| 30 |
harddrive parameters for dynamic power saving (i.e., different between |
| 31 |
running on battery as to from mains) - really does work but can kill a |
| 32 |
drive with Load_Cycle_Counts so drive life can be foreshortened if you |
| 33 |
get too zealous (i.e., very short spindown times and using a journalled |
| 34 |
file system. |
