I am having the Linkstation Duo LS-WXL. When I was trying to take the backup for the MacBook Pro via TimeMachine then it aborts the backup process and shows me error (-1). I have tried to do this many times but everytime it comes up with the same result. Now I cannot guess that what I should do in order to get this problem resolved. I will really appreciate if someone of you can help me to get this problem resolved. Please reply ASAP.
