How to get the drive letter with physical address like "\\\\.\\PHYSICALDRIVE0"?
If we give the physical address.. It should return the drive letter assigned to that drive?? help me

推荐答案

这是不可能的，因为物理驱动器可以包含多个驱动器号.
但是，您可以执行相反的操作，即打开一个卷并获取其所属的物理驱动器.

这是您可以做的.

1.枚举所有卷-GetLogicalDrives.
2.打开每个卷-例如. CreateFile(L"\\\\.\\C:", ...
3.用IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS在CreateFile返回的句柄上调用DeviceIoControl.

That is not possible because a physical drive can contain multiple drive letters.
You can however do the reverse, i.e, open a volume and get the physical drive to which it belongs.

Here is what you can do.

1. Enumerate all volumes - GetLogicalDrives.
2. Open each volume - eg. CreateFile(L"\\\\.\\C:", ...
3. Call DeviceIoControl on the handle returned by CreateFile with IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS.
