What is "EFI Boot"?
Despite the many reports that WD MyBook drives could not boot an SD Backup of an OS X 10.6 installation via FireWire... I went ahead and gave it "a try". It wasn't too great of a risk as I had a functional SD backup of 10.5.8 on another MyBook drive.
It worked fine... which was a pleasant surprise!
What I'm curious about, however, is the name given to the 10.6 backup was "Full Backup2" --- and that is how it's shown in Finder.
But when I restart the iMac with "option" depressed, this volume is shown as "EFI Boot". Does this have any significance? Why was it changed here but not in Finder... or more important: Why changed at all?
