Unable to update firmware - myBook

Trying to update firmware.  Get message that some program is trying to access the drive.  I have stopped all visible programs from but still get the same errot message.  Whagt could be running that would not show up on task manager, Windows 7?

If the drive is working I wouldn’t bother with the firmware updates. Make sure you have all the things like netframework, flash etc that are required. Also shut off your AV while you do the update.
