I upgraded to Maverick and now Time Machine will not connect to the external hard drive to back up files. The external hard drive is a Western Digital "My Book Live" 2 TB. How do I solve problem?

I would test the ext hd with another computer as my wd my book died very early too

but I took it apart and the hd itself still works it's just the external case which is defect

I can see my MB live in the finder, but when I try to connect to shares as a registered user, it won't let me.

Frustrating

I also had problem accessing my WD MyBookLive after upgrading to Maverick.

To resolve the problem, I used Connect To Server (Cmd K) to specify the IP address.

Then I enter a user id and password I created in the MyBookLive.

You can also verify that you have admin access to the MyBookLive using Safari or Chrome.

Just enter the MyBookLive IP address as the URL.
