actually there is a special bad track feature on the disks. It is at the end. It means this:
a computer measures the data it understands as = XXXMB
a pure 1-1 burning program realises it has to burn that bad track which is designed to fool it into believing that there is more data than will fit on any current disc (normally the size = 100MB).
Now, do you think that apple would allow you to pirate their OS on their OS?????? No. Disk Utility/Copy will of course respect the system apple uses.
Now worries - GM is going to kick sooooo bad.
Of course - you could spend USD1500 get ADC and have apple send you the three discs.
