It's on a G5/2.5 with Leopard 10.5.1 on the external. The drives are both 500 GB. Because it didn't worked I even installed the latest update over the existing OS on the internal. This is what I've sent to Mike about the latest CCC: I tried to copy an external ATA drive containing leopard to an internal SATA drive to have Leopard there. It didn't worked. The internal one wouldn't startup. It took 5 hours to copy and I never got a warning or error.
