I have been using a Western digital to back my macbook, but since upgrading to OS X 9 maverick it is no longer visible in the finder window?
I've used the Western digital utility and the drive passes all tests and it sees it?
updated the driver
view hard drives is turned on in preferences
Why isn't the macbook seeing it to do a backup?
