通过代码，我怎么能发送一个硬盘驱动器入睡 [英] By code, how can I send a hard disk drive to sleep

问题描述

我有很多的硬盘驱动器在我的电脑（7）。

I have lots of hard disk drives in my computer (7).

当他们不使用电源选项，给他们一段时间后睡觉。
，而因为一切都使得大量的噪音，我想送他们睡觉时，我想，不只是默认的系统超时后。

When they are not used the power option send them to sleep after a while. But because everything makes a lot of noise I would like to send them to sleep when I want, not just after the default system timeout.

在Windows（ XP及以上），最好是在C＃中，

On Windows (XP and up), preferably in C#,

我如何发送磁盘通过代码睡觉？

非常感谢提前对你的帮助......

Thanks a lot in advance for your help...

推荐答案

据我所知，这是一个ATA命令那台*降速time8 - 这意味着它是关闭驱动器本身。你可以使用IOCTL_ATA_PASS_THROUGH将命令直接发送到驱动器 - 但是我怕你会做没有不仅仅是将它设置为某些最小值（我不知道它是什么好，但它应该是在ATA规格。）

AFAIK, this is an ATA command that sets the *spin down time8 - meaning it's the drive itself that shuts down. You could use IOCTL_ATA_PASS_THROUGH to send commands directly to the drive - but I'm afraid you'd do no better than just setting it to some min value (which I don't know what it is, but it should be in the ATA specs).

编辑：看起来像古老的 hdparm的支持它，所以它必须在ATA规格：

Looks like the venerable hdparm supports it, so it must be in the ATA spec:

-y
组的IDE驱动器立即进入低功耗待机状态下，通常导致其停止运转。

-y Force an IDE drive to immediately enter the low power consumption standby mode, usually causing it to spin down.

-Y强制的IDE驱动器立即进入最低功耗的睡眠模式，导致其完全关闭。硬或软重置之前，需要的驱动器可再次访问（在需要的时候，如果/ Linux的IDE驱动程序会自动处理发出复位）。

-Y Force an IDE drive to immediately enter the lowest power consumption sleep mode, causing it to shut down completely. A hard or soft reset is required before the drive can be accessed again (the Linux IDE driver will automatically handle issuing a reset if/when needed).

由于 hdparm的（它使用与驱动器通信的底层Linux内核）是GPL的 - 你应该能够从那里婴儿床的细节，如果你没有一个ATA规格得心应手。

Since hdparm (and the underlying Linux kernel it uses to communicate with the drive) is GPL - you should be able to crib the specifics from there if you don't have an ATA spec handy.

或者，只需使用 Win32的移植
