My favorite method for this is to run

    $ find ./ -type f -exec md5sum {} \; > md5sums

in a directory before copying it (burning to CD, writing to zip, etc.).
Then just do:

    $ find ./ type f -exec md5sum {} \; | diff md5sums -

I've found that md5sum does a pretty exhaustive scan through a file
and it'll find CD write errors.  I don't know if it actually searches
every byte / block though.
