Every week I will copy the backups to external USB hard disk connecting it to windows server 2008 R2. Most of the time I will face the below message while trying to unmount/eject the external hard disk. Acknowledging the prompt I check if any window of HD is open and close if any but it always prompts the same while trying to remove safely.
This device is currently in use. Close any programs or windows that might be using the device and then try again.
Anybody has any fix for this other than restarting the server for removing the device safely?
