I wonder what some Government org like NSA would think about this? Then again, they may want us to believe this so they can get stuff back. ;-) ;-) That said, I always wondered how something can be there when it is erased. On paper, I can see that because it made a physical change to the paper but on magnetic media, it is magnetic not physical. Anyway. Dale :-) :-) -- I am only responsible for what I said ...
