Ok, my new powerbook 12" had a problem with the hard drive. But to make the story short... I would have to send it to Apple and wait 10 days to get it back. They can not even check the drive at an Apple store here in NYC. By the way, to back up the system and re install it from the back up is just not possible. I have to set all the preferences again and re isntall all the software. It was not like in OS9 that I was able to move everything from one drive to the other and still functional.
