Just recently moved and I can’t find the correct AC adapter to My Book. How do I determine the right one so I don’t fry my drive? It contains all of my backups!
Thank you!

Thank you very much! I’ll keep looking.

If I can’t find the one you’ve listed, is it possible to buy a new power cord that would work through WD?
