I’m sorry, did i say “Defeat?“
What I meant, of course, was “Victory!”
I got that 9500 to boot. I had to remove the large additional internal SCSI drive and mount it in a discarded and suspect external SCSI case. Then I used CCC to dupe the volume I was hoping to grab, and I was in business.
Mind you, removing the physical boot volume and mounting it in the drive chassis is by no means an acceptable long-term solution – in the end, I still need two bootable OSX volumes. But, enough time wasted for now.
