Encrypted time machine will not mount

Last night I “removed” my hard drive (a my book drive), for some reason instead of my usual way. I wanted to start fresh and encrypt my back up drive. I really did not mean to do it this way. Now my drive will not mount! I have tried everything! It shows if I open my disk utiliity. It shows both the physical external disc, and the logical os x extended volume named “time machine”, however that is ghosted. It will not allow me to mount it through the disk utility. If I try to run first aid, the ghosted volume disappears. I have also tried these steps through the WD my book utilities to no avail. I have also tried to go through restore mode and recover, but it just is an endless spinning wheel for hours and hours. Basically it appears as if it is already encrypted. Its is as if it started the process, since I selected it, yet it removed it. But, it does ask me for the password on restart. Any tips on how to remount? I have tried a direct plug in with both computer and drive to the wall. I have also tried different ports. As a last resort I tried to erase the drive, but it also will not let me do that. It says it is “unable to delete the core storage logical volume group."

I have read a few other threads here and so far, none have helped... so I am posting separate in hopes of a miracle! The drive is new.
