"The target disk appears to be full."

If your target disk fills before you are finished cloning to it, any files lower in the directory tree than the last file copied were not successfully copied. You can resume copying after you clear some space on the target, or select another target and start over.

Note: You may not continue copying precisely where the previous attempt left off. You may, however, remove the items from the "Items to be copied" list that were successfully copied. For example, if "/Users/bob/Documents/picture.gif" was the last file copied, you may remove all items above "Users" in CCC's "Items to be copied" list.

Check CCC's log to determine the last file copied.
