Hi - my original problem - which led to the purchase of a new backup drive - was that the old one ran out of room - time machine wasn't overwriting as it backed up - I also couldn't find a way to erase the old drive! I'm hoping that I won't run into this problem again .... but as a precaution, I downloaded the time machine editor. www.sarniasue.blogspot.com www.suegalos.com/Home.html www.sarniastudiotour.com/home.html --- Manage your account options at //www.freelists.org/list/muglo
