Question

你们要求怎样做视窗在方案上铺设硬磁盘? 我是否可以呼吁任何用户使用现场功能(或掩体-mode功能要求或IRP发送),以便做到这一点?

I ve试图实施一项方案,发送。缩略语ATA ashDBY 直接到硬盘上,但问题是,这种方法没有向系统提供信息,因此,只要系统需要冲动海滩,就会再次打开硬盘。我怎么告诉我:system? (如果系统确实如此,它就会在数据过于庞大时节省海滩和“充电”数据,而不是用小数量书写。)

(此处的整点是:通过将全系统的平流时间改为第1段,并等待磁盘上下,来做到这一点。) 我需要一个职能,在我使用我的手提电脑时,我可以在某个具体时刻叫我,而不是一个适合95%情况的通用工具。

至今为止:

我有以下感受:PoCallainr和IRP_MJ_POWER 。这样做可能是有益的,但我对地圈-地方案拟订经验十分有限(而且几乎是零动力经验),因此我确实没有想法。

更多信息:

I ve found this document about Disk Idle Detection to be useful, but my answer isn t in there. It states that the Power Manager sends an IRP to the disk driver (hence why I suspect IRP_MJ_POWER to be useful), but I have no idea how to use the information.

Answer 2

Have you tried WMI? Based on MSDN documentation, you should be able to send spindown command to HDD via WMI:

uint32 SetPowerState(
  [in]  uint16 PowerState,
  [in]  datetime Time
);

EDIT:

该守则列出了支持本年度行动计划的所有系统驱动器和驱动器:

strServer = "."

Set objWMI = GetObject("winmgmts://" & strServer & "/rootcimv2")
rem Set objInstances = objWMI.InstancesOf("CIM_DiskDrive",48)
Set objInstances = objWMI.ExecQuery("Select * from CIM_DiskDrive",,48) 
On Error Resume Next
For Each objInstance in objInstances
    With objInstance
        WScript.Echo Join(.Capabilities, ", ")
        WScript.Echo Join(.CapabilityDescriptions, ", ")
        WScript.Echo .Caption
        WScript.Echo .PNPDeviceID
        WScript.Echo "PowerManagementCapabilities: "  & .PowerManagementCapabilities
        WScript.Echo "PowerManagement Supported: " & .PowerManagementSupported
        WScript.Echo .Status
        WScript.Echo .StatusInfo
    End With
On Error Goto 0
Next

这部法典只是作为文件,从指挥线上操作。

Answer 3

我没有回答Mehrdad询问的具体问题。

However, to help others who find this page when trying to figure out how to get their disk to standby when it should but doesn t:

我发现,在“USB”磁盘上,MS Pwr 试验公司声称磁盘已经关闭,但实际上该磁盘仍在封。即便在7. <>em>上,全球磁盘时间确实很短(这意味着,即使该系统认为它已经翻了磁盘,但可能实际上不会倒。因此,Mehrdad的原始目标即使找到了正确的方式,也不会奏效。这可能与各种磁盘控制器如何实施电状态有关。
I also found that the program HDDScan successfully can turn off the disk, and can successfully set a timeout value that the disk honors. Also, the disk spins up when it is accessed by the OS, a good thing if you need to use it, but not so good if you are worrying about it spinning up all the time to flush 1kB buffers. (I chose to set the idle timeout in HDDScan to 1 minute more than the system power manager timeout. This hopefully assures that the system will not think the disk is spun up when it is not.)

我注意到,电车可以选择防止闲置锁从低频软盘中重发。

http://hdscan.com 视窗司机K 。不幸的是,Pwr 试验使你不得不首先安装了许多其他管束,但如果你能够说明如何从令人困惑的网页下载,那是完全自由的。

Answer 4

While there is no apparent way to do what you re asking for (i.e. tell power management "act as if the timer for spinning down the disk has expired"), there may be a couple ways to simulate it:

FlushFileBuffers(需要提升到开放的/C),然后向驾驶员发出ashDBY指令。
要求将光盘封顶时间排到第二位,然后在第二版后将其重新提高到原来的数值。请注意,你可能需要追随以前的价值,而不是立即跳跃。

Answer 5

我认为,能够完成你需要做的工作。如果是,源代码可在Windows Ddk上查阅。
