How to come back / recover:
Don’t afraid, all of your Data still safe .
to Come back the Drive repeat the process . but in Step-4, which is shown in this post replace “ remove ” to “ assign ”

The above method won’t work for the drive containing Operating System.
and it can also be done using System Manager>Storage Manager.
