COPYFAST is the program you want.  It does full track reads and
writes, I believe.  It's available from most RCPM systems.  I don't
think it's available on MC:CPM, but I could upload if necessary.

If you look on an RCPM for it, look for CPYFSTxx (where the xx is the
version number).  I don't recall what the latest number is.
