Did they agree to replace all the EFAX drives, even though they aren't new any more? I can see I might have to get in touch with them Got 4 from around december '19..... I also started a replacement issue with the WD support in Germany. The hotline seems to be competent. We agreed to replace one disk after the other, since they want to replace after I sent the the old one first to them. I'll see how it will go.
If there is interest I could give a update how the story went.
