The answer is "Yes". In fact, whenever you lose data while partitioning or after partitioning the hard drive on Mac, the actual data is not removed immediately. The computer system only marks that data deleted but still keeps it at the data segment. As long as the deleted data is not overwritten by new data, it can be found and recovered.
