How to find deleted partition

I have some partition table with three partitions. I deleted the third partition with fdisk and next I created new partition on the same place with the same "first and last sectors". How can I determine if the deleted partition ever existed (I don't want to recover it). Screenshots of what I did: * third partition before deletion: * third partition file system before deletion: * deleting the third partition (reboot system after): * new third partition after deletion old third partition: * new third partition file system after deletion old third partition file system: * With TestDisk we can see partition table: So again: how can I determine if the deleted partition ever existed? Maybe with TestDisk or somehow different?
