(When I say always, please bear in mind that I don't do this every day or even frequently). You'll also see calls to dd. These were attempts at "last ditch effort." I usually just use the copy command (got it from a thread entitled, "copying a dvd video," from November of 07). If dd will work but I just forgot to get the block size right, what is that supposed to be. So, here's what I'm doing with the results. Any help is greatly appreciated because am at the point of pulling my hair out (which might have actually happened had I not shaved it off).
