Product Details

Western Digital My Book 4TB External USB 3.0 Drive

If your laptop or desktop computer can’t hold all your movies, music, and important documents by itself, this external hard drive provides 4TB of additional space for safe storage and backup. Its 3.0 USB technology lets you transfer data three times faster than USB 2.0, so you don’t have to waste time twiddling your thumbs as you move around large files.

Generous Storage Space
With a capacity of 4TB, this external hard drive can store up to 307 hours of video, up to 1,000,000 songs, or up to 800,000 selfies from all your social-networking profiles.

Keep Private Files Private
My Book comes with a WD security utility that makes it easy to set up password protection and hardware encryption, building a virtual wall between your confidential data and unwelcome intruders.

Back Up Your Files
Preloaded WD SmartWare Pro software can automatically create and store a second copy of each file to help protect your data, just in case you accidentally delete something important.

Convenient Size
Although the external hard drive holds a ton of data, it takes up little space on desktops and fits nicely next to monitors. It’s also simple to toss in a bag and take on the road.

No instructions included. I plugged it in and no indication of my computer recognizing it. Hopefully I can figure how it works.
