increase windows vhd using diskpart and vhd resizer

I am trying to increase the size of a vhd using vhd resizer and diskpart.  I have a hyper v machine.  I had done this before and I think these were the same steps, but I am not 100% sure.  I just bought a 3TB drive.  I created two partitions 1.5 tb each (or whatever I had splitting it in two, they have some reserved).  I tried to make my vhd 1.4 tb, so I loaded it in the vhd resizer tool, and set he size to 1.4 tb.  This took over a full day and just finished.

Here is the link with the instructions:

I attached the vhd in diskmanager then opened a command prompt and typed "disk part", "list disk", "select disk 4", "detail disk" and I got the following.  I was expecting to see a volume, but I don't.

DISKPART> detail disk
