如何找出usb弹出的存储量与否？
[英]How to find out is storage volume on usb ejected or not?
问题描述
I have an USB device with CD Drive and storage volume. 
我有一个带有CD驱动器和存储卷的USB设备。 I can eject both of them or one by one. 我可以一个接一个地弹出它们。 When I call CreateFileA to obtain handle of ejected volume, it returns a valid handle. 当我调用CreateFileA来获取弹出卷的句柄时，它返回一个有效的句柄。
Have anyone idea, how to detect that volume is not ready for using? 有谁想，如何检测该卷还没有准备好使用？
UDP: I have an application, that can starts when the volume is already ejected. UDP：我有一个应用程序，可以在已经弹出卷时启动。 I want to identify state of the volume, when programm is running 我想在程序运行时识别卷的状态
