YES! Success! VCenter back up and running with clean .VMDK files. I still have to remove the backup folder and contents, but will probably wait a few hours before doing so.
Thank you VERY much for the guidance.
I am down to 2 VMs that need fixing from this orphaned snapshot corruption problem. Both are special cases. I will probably post the next one to this thread shortly, as I feel that it is all related to the same type of issue.
Thanks again for all of your help!
