I have 2 MBLD on the same network and have been given different names. One is 6TB and the other is 8TB and are used for storing video files. While I can see and can access both MBLD from my PC, I can only see one from my PS3. The only way to see both on my PS3 is to reboot the drive that I can’t see.
If one MBLD is working fine with PS3 then you should not face any issue using the second one as well. For troubleshooting the issue you should try contacting WD’s Technical Support about this.
