Report Not a true copy/clone in Retrospect bug reports Posted October 19, 2014 Clarification to my previous comment: The USB2 drive was connected to an USB3 Hub connected directly to an USB3 port of a MacPro. Too manny cables there. And yes, the additional information seems s to be stored only when discs are not connected via USB. If you swap disks between different connections you can cheat yourself. Sorry! - The problems are nevertheless true.
