In windows is it possible to know what kind of disk we are dealing with from a c/c++ program? forget about gpt or mbr, how to know whether it is basic or dynamic? Program input can be drive letter or any info related to disk, output should be dynamic or basic. No need of a direct way of doing, even if it is lengthy process, its okay. I couldn't find much in msdn. Please help me out.

推荐答案

windows 中有一个方法，但不是直截了当的.

There is a way in windows, but it's not straight forward.

没有直接的 API 来确定磁盘是基本磁盘还是动态磁盘，但是所有动态磁盘都将具有 LDM 信息.

There is no direct API to determine if a disk is Basic or Dynamic, however all dynamic disks will have LDM Information.

因此，如果一个驱动器的分区上有 LDM 信息，那么它将是一个动态磁盘.

So if a drive has a partion with LDM information on it, then it's going to be a dynamic disk.

带有 IOCTL_DISK_GET_DRIVE_LAYOUT_EX 控制代码的 DeviceIoControl() 方法可用于获取此信息.

the DeviceIoControl() method with the IOCTL_DISK_GET_DRIVE_LAYOUT_EX control code can be used to get this information.

这是一篇包含示例控制台应用程序的帖子你要的.
