I just got a new 2.2MPB to replace my old 867 Titanium. When I plug my older external firewire drive i've been using with my titanium, and boot up the new MBP, it just sticks at a blank screen. No Apple Logo, no boot time-thingy..just a blank screen. NOW, here is where it gets kinda weird, I have a Firewire audio interface [m-audio 810], when I plug THAT directly to the MBP and THEN the chain the ext. drive off that, it boots fine and I can see files on the drive. I tried my friend's ext fw drive as well, and after a couple reboots, it finally saw HIS drive - but only after a couple reboots? Does anyone have any ideas of what's going on - or had a similar experience?
