[QUOTE="tewatson, post: 1049165, member: 68855"] The only thing that shows up when booting with the Option key held is the Macintosh HDD. This is using the FW800 port and a bootable WD My Studio drive, using a disk backup made with SuperDuper. Identical setup works on my new MacBook Pro. Can't find any setting that might be inhibiting an external drive boot. Tom [/QUOTE]
