Purchased 500GB WD MY BOOK Essential last night to use as backup for MacBook Pro. During install it said there was updated software and did I want to install it. I said yes. Should have waited til entire install was done. After that everything went to hell. Never asked me if I wanted to use Mac’s Time Machine software instead of its Smartware. After the update was installed it asked for the password I had set. I entered it (I know it was correct!) but WD would not accept it. Said invalid. I used the “uninstall” Smartware app in attempt to start over. Now I have a “locked” external drive with nothing on it and my Mac will not recognize it (not listed under “devices”). Is there a way to reset the whole shooting match and start over from scratch and use my Time Machine app instead of the stupid Smartware?
