I have an external hard drive on which I have backed up files several times. Some files were modified between backups, others were not. Some may have been renamed. Now I'm running out of space, and I'd like to clean up duplicate files.

My idea was to md5sum every file on the drive, then look for duplicates, and diff the relevant files (just in case, haha). Is this the best way to do this? What are some other methods of checking for duplicate files?
