Unique Identifier Conflict on Two Drives

WD External Drives External Drives for Mac

I am using two My Passport on the same Mac. I am trying to backup one to the other with Carbon Copy, but cannot do so because they have the same “unique identifier”. How can I assign different UIs?
Thanks,
David

Hello,

The only thing that comes to my mind is the name of the units.

Can you please try changing the name of drive?
