Hidden partitions are normally small and have nearly no free space. Meaning that you can not test writing and reading from this partition without overwriting the data in the partition (even if it was not hidden).

Depending on the method used to hide the partition you might just be able to repartition the drive to unhide it. But you would lose the data on the partition in this case.
