给定一个卷(如Z:),如何判断该卷是否位于“可移动”的设备上?

您可以打开该卷并发出IOCTL\u STORAGE\u QUERY\u属性;这将返回具有RemovableMedia属性的存储设备描述符。我相信这与CM_DEVCAP_REMOVABLE(不是100%确定)是一样的。至少它报告说“固定”USB闪存驱动器是可移动的。

HANDLE hFile = CreateFile("\\\\.\\Z:", FILE_READ_ATTRIBUTES, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
if(hFile != INVALID_HANDLE_VALUE)
{
    STORAGE_PROPERTY_QUERY StoragePropertyQuery;
    StoragePropertyQuery.PropertyId = StorageDeviceProperty;
    StoragePropertyQuery.QueryType = PropertyStandardQuery;
    BYTE Buffer[1024];
    if(DeviceIoControl(hFile, IOCTL_STORAGE_QUERY_PROPERTY, &SotragePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY), Buffer, 1024, &BytesReturned, NULL))
    {
        PSTORAGE_DEVICE_DESCRIPTOR StorageDeviceDescriptor = (PSTORAGE_DEVICE_DESCRIPTOR)Buffer;
        if(StorageDeviceDescriptor->RemovableMedia)
        {
            printf("Z: IS removable\n");
        }
        else
        {
            printf("Z: is NOT removable\n");
        }
    }
    CloseHandle(hFile);
    hFile = INVALID_HANDLE_VALUE;
}
