My Book for Mac power cord

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!

Hi romafo2004,

Please help us with the model number of the drive so that we can give you the exact specification of the power adapter for your My Book device.

I don’t have a model number. Does this help?

WD My Book Home Studio 500GB Quad

Part #: TP439ZM/A

Hi romafo2004,

Please find the specification of the power adapter for your device mentioned below.

12 Volts
1.5 Amps

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?
