Can I reset my password - Western Digital My Book Essential Edition (WDG1U5000N) 500 GB Hard Drive

Hold the reset button in, and plug the data cable and the power cable back into the unit. Wait until the lights on the unit light up and then count to 10 before letting go of the unit's reset button. The unit boots up and the "AutoPlay" window displays on the computer screen. Then use default username/passwd to get into the WD hard drive. The default user name is "admin" and default passwd is "123456" or "admin"
