在windows7 – 32位系统上获取有关磁盘驱动器的信息

当我在Windows XP-32上运行下面的代码，我得到下面的结果。

我只插了一个USB笔驱动器

请看这两个结果…

我已经在两个系统（XP和Windows7）插入一个相同的USB设备，但结果各不相同…

该程序可以在没有安装Windows DDK的情况下进行编译（只需要安装Windows SDK，例如与Visual Studio一起安装）。 该程序产生如下输出：

因为只有通过驱动器号才能访问的设备我们感兴趣，所以程序从GetLogicalDriveStrings函数开始枚举系统中的所有逻辑驱动器。 对于每个驱动器，我们可以使用IOCTL_STORAGE_QUERY_PROPERTY来获取VendorId ， ProductId和ProductRevision 。 使用IOCTL_STORAGE_GET_DEVICE_NUMBER允许我们获得驱动器types（如CD / DVD或磁盘/软盘）。 此外，两个数字： DeviceType和DeviceNumber在系统中是唯一的，我们可以使用这些数据作为驱动器的设备实例（使用SetupDi – 函数）的基础。

由于软盘和磁盘设备具有相同的DEFICEtypesFILE_DEVICE_DISK我演示另一个函数NtQueryVolumeInformationFile与FileFsDeviceInformation参数来获取设备的这样命名的特性 。 该特性是从其他磁盘中退出软盘的最佳方法，并为设备枚举（ GUID_DEVINTERFACE_FLOPPY或GUID_DEVINTERFACE_DISK ）select相应的类和接口GUID。 我们获得了与SetupDi API枚举的所有设备的DeviceType和DeviceNumber。 我们找出哪个设备有哪个驱动器号。

更重要的是设备的层次结构：父母/子女关系。 为了演示这个，我在代码示例中使用了CM_Get_Parent和CM_Get_Device_ID函数。 所以我们可以看到哪个USB设备有哪个存储设备。

我显示了一些有关find的设备的信息。 您可以将示例中的API与IOCTL_MOUNTMGR_QUERY_POINTS （请参阅使用IOCTL_MOUNTMGR_QUERY_POINTS ）或FindFirstVolumeW ， FindNextVolumeW和GetVolumePathNamesForVolumeNameW （请参阅http://msdn.microsoft.com/en-us/library/cc542456(VS.85).aspx ）组合以获得更多详细信息如果需要。

更新 ：顺便说一句IOCTL_STORAGE_QUERY_PROPERTY返回的缓冲区具有像STORAGE_BUS_TYPE BusType （ BusTypeUsb ， BusTypeFibre ， BusTypeSd等）等另外的字段。您还可以使用IOCTL_STORAGE_QUERY_PROPERTY要求另一个信息，如StorageDeviceUniqueIdProperty或StorageDeviceUniqueIdProperty等如果你想有更多的USB特定信息，我build议您http://www.emmet-gray.com/Articles/USB_SerialNumbers.htm其中显示了;IOCTL_USB_GET_NODE_CONNECTION_INFORMATION_EX ， IOCTL_USB_GET_NODE_INFORMATION和IOCTL_USB_GET_DESCRIPTOR_FROM_NODE_CONNECTION 。

更新2：由于在stackoverflow.com中的邮件大小限制，我在http://www.ok-soft-gmbh.com/ForStackOverflow/EnumMassStorage.c中放置了程序的扩展版本。; testing输出看起来像下面http://www.ok-soft-gmbh.com/ForStackOverflow/EnumMassStorage.txt

更新3：我发现了一个错误，并更新了代码。 请使用最新版本的代码，并确认您的问题已解决。
