Locked out of network My Book Live 2Tera--

I changed PW on my drive and it will not recognize it–drive works otherwise OK–I just can not get  into my setup area

PS  I guess what I am asking is there a way of getting rid of this PW without erasing the drive?

Per the instruction manual, press the reset button for 4 seconds.

Thank you—that solved my problem.  Next time I should probably read the manual first–but sometimes it is faster to ask the question from other users than trying to read 200 pages of manual.
