I have been trying to get a 3.0TB drive to show up using gpart show

dmesg show the following:

ada1 at ahcich1 bus 0 scbus1 target 0 lun 0
ada1: <HGST HDN724030ALE640 MJ8OA5E0> ATA-8 SATA 3.x device
ada1: Serial Number PK2234P9H997BY
ada1: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes)
ada1: Command Queueing enabled
ada1: 2861588MB (5860533168 512 byte sectors: 16H 63S/T 16383C)
ada1: Previously was known as ad6
GEOM: ada1: the secondary GPT header is not in the last LBA.
GEOM_PART: integrity check failed (ada1, GPT)

ls /dev shows ada1 and nothing else (like adap1 and ada1p2).  It is 
partitioned with two primary partitions (GPT)  one is ntfs for windows
and I want to create a UFS files system on the other but it doesn't show 
any partitions.

Any help with this?
