I was not questioning your opinion of undelete utilities. What I am  
questioning is this: If undeletes are a farce (which I will grant for  
the sake of this discussion), what difference does it make if Apple  
is writing to the new drive space or old drive space?

I can see where undelete utilities would not want Apple to write on  
the new space as that would overwrite newer files (if I am  
understanding this correctly). But if you have a current backup, why  
does it matter if Apple is writing to old drive space or new drive  
space?
