Hat geantwortet auf: WD My Passport Ultra 2TB not showing in MacBook FinderI had this same problem and concluded that the drive had crashed or data was corrupted. However, it had been warm and the drive had been plugged in for a while. I tried it in a Windows PC and then later again in my Mac, but still didn't work. Finally, I put it in the refrigerator and then plugged it in to another Mac and I was able to read it and extract the files I wanted. Not sure if cooling it down was the answer, but this has also worked for me in the past with other drives.
