Failed to unwrap key

I purchased my 3TB WD MyBook 2014. No password was set. I attempted to read the key using the instructions and scripts from “https://github.com/themaddoctor/linux-mybook-tools,” but without success. I now wanted to use your reallymine getdek to find out which chip is actually installed. Unfortunately, your program closes after several hours with the following message:

root@mint:/tmp# ./reallymine getdek /dev/sdd error running getdek: Failed to unwrap key

I am now relatively at a loss and would be very grateful for any advice you could give me.
