Consolidating VMWare Snapshots Not Attached To VMDK

Good morning,
We had a very interesting issue that I'll try to outline as much detail as possible:
Our Datastore continued to run out of space, which hosted a file server.  We expanded the Datastore a couple times and it kept doing it until we were out of space to allocate.  We didn't expand the guest (which has a 2TB volume), but it continued to run out of space.  What I noticed was a couple new hard drives (vmdks) in the folder.  They were attached to anything and we didn't run snapshots on the volume, so we were perplexed.  

Eventually, it was determined that our Unitrends backup system creates a snapshot to do its incremental backups, but it failed because there wasn't enough space on the volume and the snapshots just sat there.  Before we knew what the disks were we deleted one of them, unmounted the 2Tb VMDK and remounted it to get the server up and running.  Now there is a ton of 0KB data.  The one VMDK we understand is gone and we could restore some of the data, but there is now a 400Gb snapshot sitting there that I want to consolidate back into the 2Tb volume.

Is this possible?  The 2Tb volume doesn't seem to know that its missing any data or dependent on snapshots anymore.

I appreciate your help.
