    All that is true but the problem was the of= was smaller than the 
if=. I just checked and dd has my entire F7 copied to the new hard 
drive. I just had to make the partition a small bit bigger than this 
one. It is there and perfect!


    So dd works fine if the partition it is going to (if=) is at least a 
bye larger.

Now to have a big scotch :-)
