将驱动器号转换为分区 ID/磁盘 ID [英] Converting a drive letter to a Partition ID / Disk ID

问题描述

给定驱动器盘符，我如何获取 OSImage InstallTo 分区 ID 和 磁盘 ID 而不使用注册表?

Given a drive letter, how do I get the OSImage InstallTo Partition ID and Disk ID without using the registry?

推荐答案

WMI 类 Win32_DiskPartition 正是我所需要的.现在来弄清楚如何使用 WMI 从驱动器号中获取此信息.

The WMI class Win32_DiskPartition is what I need. Now to figure out how to use WMI to get this information from a drive letter.

Win32_LogicalDisk 也很有用，MSDN 示例，以及此 stackoverflow 答案.

更新:嗯，这行不通！无论如何不在 Windows 安装程序中(Windows PE 中缺少 WMI!!) 所以我使用了另一个答案 QueryDosDevice(例如 \\.\PhysicalDisk1\Partition0)并破解它一起.这让微软很不爽，在你的安装程序中接受一个该死的路径.

Update: Hmm, this doesn't work! Not in the Windows Installer anyway (WMI is missing from Windows PE!!) so I am using the other answer QueryDosDevice (e.g. \\.\PhysicalDisk1\Partition0) and hacking it together. This sucks Microsoft, accept a damn path in your installer.

答案: IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS 用于获取磁盘 ID.DeviceIoControl IOCTL_DISK_GET_PARTITION_INFO_EX(感谢 TLama)为我获取Partition ID.

Answer: IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS works to get the Disk ID. And DeviceIoControl IOCTL_DISK_GET_PARTITION_INFO_EX (thanks TLama) gets me the Partition ID.
