find . -name "*"To dump the contents to a file, use the > followed by the filename. So to list the contents of a volume into a file called source.txt, use:
find . -name "*" > source.txtTo do the same on the target volume, change the working directory to the target location and re-run, this time with a different name, like target.txt:
find . -name "*" > target.txtTo then compare the two, you could use diff:
diff source.txt target.txtYou could also use a third party tool to compare the files graphically. While there is a tool built into OS X for this, I like to use TextWrangler.
