Thanks for the tip. What I ended up doing was to isolate the old machine instead of the new machine. I restored the latest SuperDuper! backup to an empty partition on an external drive, and then set up the new mac with the backup. All went just perfectly. My feeling is that the old machine has some problems. Last year, it had started acting like the hard drive was going bad. On advice from the Apple Store that an on-the-fly repartition could be the problem, I backed up the computer, repartitioned the drive and restored. All had worked fine until the attempt to move everything over to the new machine. My suspicion is that part of the hard drive on the old machine is bad (by which I mean is that there are new bad blocks). I'm going to run a block by block test over the next few days to see what happens. Cheers, and thanks again, Bill
