I just got the MyBook Thunderbolt Duo and formatted it so I can have a dual drive but it never mounts properly. I used the WD application, I’m running El Capitan on my Mac (version 10.11.3) and each drive mounts for amount 3 seconds and then automatically ejects without me doing anything. What am I doing wrong? I then try to format it with Disk Utility and can’t get anything to work as “it’s not journaled”… Any help would be great! Thanks.
Hello, have you tried using a different thunderbold cable and a different thunderbold port on your computer?
