I have the same problem, and have searched endlessly for a solution - there isn’t one.
Google “My Book Essential Not Recongized Windows” . . . there’s millions of search results and NO SOLUTION!
WD’s “my book [non]essential” / “passport”, etc., are POSs of the lowest form - the company can’t provide fixes, and you’ll only waste more time and money following the well intended advice to buying new cables, re-installing drivers, patches, blah blah blah.
ALL of my 1Ts eventually stopped being recognized - of course, not until I had saved important files that now are unretrievable.
Save your time, money and patience, and use a cloud service. WD external drives are junk and customer service is ineffective.
