How to Open a Western Digital MyBook USB Drive.

Step 4 Tabs

So do both sides of the cover like in the previous steps. Once that is done you'll notice its still stuck on there.

There are some tabs on the bottom of the drive that hold it in, press them in with your screw driver and the cover will come off.

This is the only step you need to get the case off -- if you depress the tabs on the top and bottom as shown in the second photo here the case will slide apart.
