I, for one, would love to see this type of code in the standard FreeBSD distribution. I know some people have argued that spinning the disk down doesn't save that much power since it takes more to get it back up and running again than it does to just keep it running. I think some of us, however, are simply looking for a peace and quiet when there's basically no reason to have the drive running. It certainly wouldn't hurt to make the code available, regardless of what viewpoint a person may take. Thanks for going to all of the work to do the ioctl! I would have done it myself but I'm just too busy with real work these days. /raj To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
