So I tried to do a copy to my internal disk from a backup, and it strangely kept giving me errors without completing. The error said something to the effect that there wasn't enough disk space. So I finally just used Disk Utility to erase the whole internal disk, and then the copy from my backup went without a hitch. What happened? Why would a SuperDuper copy find itself without enough room? (The disk that the backup was made from had plenty of extra room.) SuperDuper is supposed to be replacing what was on the disk with what is in the backup for that disk.
