My Passport blocked on new laptop. Unlocker demands unkown password

Hi, I started using My Passport to backup data from my old laptop without ever using or setting up WD Security. Now I need to transfer data to my new laptop the drive is blocked by WD Unlocker which demands a password. I never set a password and have no way of creating one on my old laptop because the device demands a password before making changes. Please advise! Cheers, Yogi
