Failed to enable ownership on SuperDuper BackUp

[Anne West]

I just tried to do an Erase "SuperDuper BackUp" (that's the name of my HD), then copy files from HD.
It failed due to unalbe to enable ownership on SuperDuper BackUp.
I have had problems with my back up drive. That's why I erased it and reinitialized it.
The Super Duper log showed this:

Any ideas of what might be going on?
Thanks,
Anne
