danielph, if you have the latest Firmware Release for the Western Digital My Book Live, then following the procedure described in the User’s Manual should suffice.
This would mean:
In a Finder window, click MyBookLive under the shared items in the side bar.
If presented with an authorization screen, select Guest, and then click Connect to display the Public share.
Additionally, a more direct approach would be as follows:
In Finder, click Go and point to Connect to Server.
Trancer:> Your reply works fine if I want to use the drive as a backup which I am doing.> My question though was how do I access the drive TimeMachine-backup once there is a backup on it whithout entering the time machine app. In other words choosing the server named TimeMachine-backup in finder. Using the guest account does not work. There either has to be some kind of user name and password or another way to access the contents of this drive.> Greatful for any solutions
danielph, the Network Share used for Time Machine backups is only accessible using the Time Machine application. It displays a specific share designed solely for said function.
