Hi Dave
Thanks! I found that before, but still wasn't sure what to do excatly, you pretty much just say "boot from backup drive and perform the restore". I guess, since transferring to a new disk is a rather delicate operation for somebody who hasn't done this before, I would prefer a step-by-step guide on how to do it.
But I think I figured it out: I booted from the backup USB-Drive, went to Disk-Utility to format the new drive "Mac OS Extended (Journaled)", then launched SuperDuper! and chose "Restore - All files". It has copied 10% so far...
If this does the Job, then TWO THUMBS UP for SuperDuper!
If you find the time, I think a FAQ in the forum on how to do this would help many others.
Cheers
