I'm trying to copy the data on my HDD to a new Crucial M4 128GB SSD, which I would like to replace with my HDD. The HDD is still in the MBP and my SSD is connected via USB by a external SATA controller. I'm trying to clone the HDD using this solution: https://discussions.apple.com/message/15260335#15260335 I've set my Source to my Toshiba drive and selected my SSD for the destination. When I press the Restore button I get this error: Restore Failure Could not validate source - error 254 Does anybody know why I get this error? I have tried to restart in Recovery Mode and use Disk Utility from here. Still same problem. I'm running Lion.
