This probably won't help you that much now, but best practice for ext[234] file systems is after you clone them using dd, you should run the command "tune2fs -U random /dev/sdXX" to reset the UUID to a new random value. For XFS, the command is "xfs_admin -U generate /dev/sdXX". For ntfs, the advanced utilities have a --new-serial option to ntfslabel. It's *always* a good idea to make sure that the UUID is reset after cloning a file system, to avoid this sort of problem.
