Cannot access and unlock external WD Passport

I bought an external USB WD Passport portable drive a few years back. It worked properly for a few months and then would not mount.

I can see the drive is active and still reports data but the unlock feature no longer works.

I get the following error which I don’t understand:

“YOU MUST RUN THE WD DRIVE UNLOCK APPLICATION FROM THE WD DRIVE UNLOCK CD ASSOCIATED WITH THE DRIVE YOU WANT TO UNLOCK”

CLICK EXIT, LOCATE AND OPEN THE RELATED WD DRIVE UNLOCK CD AND THEN RUN WD DRIVE UNLOCK TO UNLOCK THE DESIRED DRIVE."

First of all, I installed this device on my Mac Pro which has no CD drive. I mounted the drive and used the utility that was loaded on the device.

What does this error mean? I downloaded a new copy of the software but the original unlock SW isn’t working and it used to work.

I realize my device is out of date but your product worked for a very short amount of time and I’d like to see if I can get the data off it.

Hello,

Please refer to the following KBA article: How to remove (disable/hide) the Virtual CD (VCD) for Windows or Mac OSX on a WD My Book or WD My Passport
