You've misunderstood what I said, Mike.  I had said, earlier in the thread, 
that RW disks should be treated as temporary only.  I was speaking of the 
lifetime and storage requirements of CD and DVD as being the same - and I did 
add 'IMO'   A well burned and carefully handled and stored CD or DVD should 
have quite a long lifetime.  I would never use RW disks for anything other 
than very short-term storage.  I did, for instance, use a couple just before 
I installed FC6, just in case I made a boo-boo and formatted my FC4 /home, 
instead of another directory that I intended to use for my FC6 /home.  The 
life expectancy for that need was 24 hours.
