WD Quick Drive Format Software Disaster

I chose the wrong letter and used it on the wrong drive, a WD 10TB My Book Desktop External Hard Drive.
I caught my mistake almost immediately!
Within a second or two.
I can’t get back in.
It is just a local disk now, completely empty.
It was filled.
Is there an easy fix?
Or, do I now need data recovery software?
Thanks in advance for any help!
