I typically use 'rsync -av -c --dry-run ${dir1}/ ${dir2}/ ' (or some
variation) for this. rsync works just as well on local disks as
remote. This isn't as strong of a comparison as even an md5, but it's
not a bad one and gives you a quick compare.
You can even use git for this: 'git diff --no-index ${dir1}/ ${dir2}/'
and that would be a stronger comparison.
