Hi Experts,
Quite a lengthy title, I know.  Sorry.
Here is what happened (three times now).  
I had created a new instance in the Compute Engine in Google Cloud.  Server 2012 R2.  I added two new drives for data.  The first drive formatted and appeared properly.  While trying to create a volume on the second drive it gave me an error during the Add access path Task.  Said this "Failed to mount path - Invalid Parameter" and the next task - Update cache never completed.  What then happened is that the partition type on the first drive I had setup changed to Unknown and was inaccessible.
Since I had no data on it, I just reset both disks and reinitialized them and went on with a furrowed brow.  Concerned but thinking I did something goofy.  Then later the same thing happened again when I had data on one of the drives and was trying to add a third drive.  Same thing.  Failed to mount path - Invalid Parameter blows up a different drive on the system.  
Now the third time.  I had a drive with data on it that existed previously on the first instance and that I had detached and added to a new instance.  The drive with data was seen fine on the new instance.  When I attempted to initialize the new drive it gave me  the same error and the partition type of the good data drive changed to unknown and my data was gone.  I detached it immediately and reattached it to the old instance but it was still hosed.  I cannot figure out if this is a problem with compute engine or Server 2012 r2.  I have worked extensively with 2012 r2 in vsphere and never had a problem like this, ever...   I am very skeptical now of the compute engine and wonder if anyone has had this issue.   I have looked extensively on the web and can find nothing myself.
Any help would be appreciated as I am supposed to take this server live within a week.

Hello,
I am replying here with the answer.  Surprised that no one at all deigned to comment on my question.  Maybe I was not clear enough.  I ended up having to pay for google support when searching for the failure message brought no search results.  Seems that the best practices of windows server do not apply to google cloud, compute engine practices.  
Anyway here is the answer and I hope it helps someone else some day.
Turns out that you cannot use the server manager wizard in server 2012 r2 to manage your disks.  Search for adding or resizing persistent disks.  Link here;  https://cloud.google.com/compute/docs/disks/add-persistent-disk
