【中文标题】如何在 Windows 上获取磁盘的标识符?【英文标题】:How can I acquire a disk's identifier on Windows? 【发布时间】:2012-04-06 10:37:12 【问题描述】:

如何在 Windows 上检索磁盘的标识符?不要与卷标识符混淆;他们是两个不同的东西。磁盘标识符是驻留在 MBR 中的 4 字节标识符(如果使用 GPT,则为 16 字节标识符)。如果您运行 diskpart 并查询磁盘的详细信息,则它是标记为“磁盘 ID”的值。

我已经浏览了所有看起来相关的 MSDN 文档,但我还没有找到能够做到这一点的任何东西;不过,显然有可能,因为 diskpart 能够从某个地方获取此值。

我总是可以调用 diskpart 作为最后的手段并解析它的输出,但我真的更愿意避免这样做。有谁知道我如何以编程方式获得这个数字?

【问题讨论】:

你可以打开\\.\PhysicalDrive0的文件句柄并直接读取MBR,假设你有管理员权限。 【参考方案1】:

您可以使用Win32_DiskDrive WMi 类和Signature 属性。

查看此示例应用

此代码返回

和磁盘部分

【讨论】:

我特别希望避免 WMI,因为代码太糟糕了,但看起来别无选择。谢谢。 @CollinDauphinee: 不必使用WMI,IOCTL_DISK_GET_DRIVE_LAYOUT_EX io 控制代码将返回Mbr.SignatureGpt.DiskId 中的值。【参考方案2】:

您应该可以使用WMI 来完成此任务。

您寻找的数据可能是Win32_DiskDrive 类的DeviceID 成员中的数据,否则您将不得不进行实验:)

【讨论】:

【参考方案3】:

在命令行中运行以下代码获取附加到系统的磁盘的 MBR 签名(十进制):

wmic diskdrive get signature

在命令行中运行以下代码获取系统上设备的磁盘 ID:

wmic diskdrive get serialnumber

注意:如果外部驱动器(例如 Pendrive)连接到您的机器,它将在上述命令的输出中列出。
