windows 7 - Partition does not have a volume

When I run DiskPart, I have a Disk 0 and a Disk 1. On Disk 0 there are 3 partitions. Partition 3 has a size of 238 GB.

When I run List Volume there is not a matching volume with a size of 238 GB.

Is there a way to manually create a volume attached to this partition (without deleting the data on the partition!)?
