My book 4TB world edition

how do you reset pass word on this version of the world series?

Miller-Village, you should be able to reset the Administrator Password back to “Admin” on your Western Digital My Book World Edition II Network Attached Storage by pressing the “reset” button located in the back of the device for a few seconds. You will need a paperclip for this.

Regards,
