Greg,
After I reconnected the external drive, the question mark went away. However, there was still an exclamation mark on the laptop. I ran the troubleshooter on it and was led to another troubleshooter, and then another - - -
Long story short:
WD SES DEVICE DRIVER SOFTWARE NOT SUCCESSFULLY INSTALLED.
Please consult with device manufacturer for assistance in getting the device installed.
Do you have a shortcut for that?
