Use hdparm -Y to spin it down immediately, or hdparm -S<n> to set a |
| 10 |
duration of idle time until it will spin down automatically. See the |
| 11 |
hdparm man page for the -S parameter and more information. |

|

You can set the -S command in /etc/conf.d/hdparm. If you want the drive |
| 14 |
to spin down right after booting, do this in /etc/local.d/. |
