When you click the Safely Remove Hardware icon in the notification area on a Windows Vista based computer, and then you click Safely remove Device_name, the device may not be removed as expected. Additionally, you do not receive a message that verifies whether the device was safely removed.
Note This problem occurs only when you left-click the Safely Remove Hardware icon in the notification area and then click Safely remove Device_name.
This problem occurs because of a timing issue in which allocated memory may be released while the system is removing the selected device. When this behavior occurs, the system can no longer find the information about the selected device. Therefore, the device is not removed.
