Trying to fully erase my My Book Essential 2TB 3.0 usb, I have firewall down and other backups ceased, no apps open and it says the drive is in use. I have hard and soft booted several times, same issue. And got the notify on firmware update, when I tried to install it is says error The app has encountered an unexpected error and is not exiting.
It has been backing up fine and diagnostics pass. I just want to wipe it and start over. Running Win 7, all windows updates are installed.
