Thanks for your reply Tony.

First I used df and realized there was a big problem.  That threw me for 
a loop.

I also used du but of course it included the /mnt drives.  Only found 
the -x parameter today.  Since I suspect the /mnt/name files (they were 
the target) I can check with du -x.

The copy did not complete sucessfully because the target ran out of space.

I'll shut down, re-install the old target drive and give you the info 
you need later today.
