WD My Book Will Not Unlock Please Help

ok so I bought a WD My book from a friend of mine and I have been going thru **bleep** trying to get it to open , I have been dealing with WD support for 2 weeks and they have done nothing but send me to post on here that i have already read and ask me to explain the same thing over and over again… so I have gave up on getting the issue resoved by customer support with that said I figured maybe someone here might be of real help… so let me explain I have spent hours reading anything i could find and have downloaded all the drivers and software I can find and tried everything and nothing is working…

details: its a WD My Book (WDBACW0040HBK)

I use a Macbook Pro 2.66ghz 6gb ram 128gb SSD running OS X 10.10

also have a 2.87ghz 6gb ram 500gb HD windows 8.1 pc as well

Hi there,

Have you tried to unlock the drive on a different computer, this is not normal. You can also try to re install the drive security to see if you can unlock the drive.
