The question in my mind is whether Disk Warrior's problem with the i7 is merely not having Apple system software for booting a DVD on the i7 or whether there is a problem with the Disk Warrior application and the i7 processor. I asked ALSoft's tech help about the technique I intend to use to rebuild the directory on the i7's hard drive and the answer was that utilizing Target Disk Mode to rebuild the directory of a computer's hard drive is just fine.
Rather than use a bootable external hard drive, I can completely avoid the i7 problem by putting the i7 into Target Disk Mode and boot from my Mac Pro that already has the latest DW version installed.
