I have checked the help window. I didn’t find there anything which would help to solve my problem.
I did install WD Discovery. It has two tabs: “Storage” and “Apps”. My drive shows up in the storage tab when it is connected to my PC. However, only thing I can do there is to eject the hard drive. When I select the “Apps” tab, I see multiple options. One of them is “WD Security”. According to user manual I should be able to set up the password by clicking the “WD Security” app. However, as I explained, it opens a pop-up window which says “Attach a supported WD drive”. “My Passport”-hard drive, which I bought is “supported WD drive”. However, for some reason, the security app does not work for me. Not sure if should return the product or if there is a way to get it working.
Please let me know what extra information you would need about my drive and system. The specifications for the drive which I bought can be seen behind this link: https://support.wdc.com/product.aspx?ID=236. I have black 1 TB drive.
