I believe the ProSel 8 "Volume Copy" will copy volumes without
regard to file structure and with the option to copy bad blocks as
all zero (I may be mis-remembering here).

I have always felt that a copy utility should pause on error(s),
and present the option to not pause--this is an obvious recovery
strategy--yet very few do it.

I'm not aware of any Apple II program with this capacity--but I'd
like to find one.  ;-)
