Unknown error

[Jay Zimmer]

On one of our MacBooks, SuperDuper gives a "Failed to Copy" message. Checking the Log, it seems to have done a lot before the last line, which is in red, and says: "Error ****FAILED**** result=256 errno=22(Unknown error:0)" What does this mean, and, what should I do? Thanks

Is your backup drive full?

[Jay Zimmer]

Yes, it was. It had been partitioned since it was twice as big as the HD. I forgot to change it back when a new larger HD was put in the MacBook, which finally was using up enough space to cause the problem. Now it's all back to equal size to the HD and SuperDuper ran perfectly. Thanks!
