Smart backup and storage.
The world''s best-selling external hard drive now features a new, smart, visual backup solution that protects your data automatically.

Product Features
Smaller, sleeker, more streamlined design - We''ve made these award-winning drives even smaller, sleeker, and more elegant. As always, this book-like shape takes up minimal space on your desk and allows two or more My Book drives to nestle neatly together like volumes on a shelf.

See your backup as it happens - Seeing is believing. Visual backup displays your content in categories and shows the progress of your backup.

Protect your data automatically - Relax, your data is secure. Automatic, continuous backup will instantly make a second copy whenever you add or change a file.

Bring back lost files effortlessly - Retrieve your valuable data to its original location whether you''ve lost all your data or just overwritten an important file.

Take control - Customize your backup, set drive security, run diagnostics, manage the power settings, and more from the WD SmartWare control center.

Drive lock - Gain peace of mind knowing that your data is protected from unauthorized access or theft with password protection and 256-bit hardware-based encryption.

Illuminated capacity gauge - See at a glance how much space is available on your drive.

USB 2.0 interface - A simple connection that offers convenience and compatibility among multiple computers.

Power miser - My Book external drives are designed to save energy. WD GreenPower Technology  lowers internal drive power consumption by up to 30%, a sleep mode reduces power during idle times, and a power-saving feature turns the drive on and off with your computer.

Planet friendly - We designed a small retail box from recycled materials to minimize waste. We encourage you to recycle it.
