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. Chris -- Christopher S.
