Unlocked Passport for Mac "Failed to enable ownership" using SuperDuper

I have a new Passport for Mac (a replacement for a defective one) and when I use it (unlocked) with my SuperDuper backup probram is gives me a message that it "Failed to enable ownership . . . "

When I eject the drive, and disconnect it, and then reconnect it the drive is “enabled.”

How can I keep the drive 'enabled"?


Does the drive mount the “unlocker” partition?

The software could be trying to use this as the backup destination.

Does the same thing happen if you use another software like Time Machine?
