问题 hi I am using a Kingston DT4000 G2 USB drive with password protected. I could track disk plug in & out event under windows by calling RegisterDeviceNotification(), and receive notification by WM_DEVICECHANGE; While the problem is the media is not available till I input password. Before decryption I could see the device and system will show "Please insert a disk into USB drive (E:)". But I can't capture the event when data is decrypted and media is really available to me. Is there a such event
