I have taken out the superdrive of my MBP and am running 2 ssds in a raid0 configuration. Upon a cold boot the laptop boots and hangs eventually giving me the the Grey circle with the slash though it. When I hold the power button down to force a shutdown and then restart it boots fine taking about 30 seconds to load the os. I don't like having to bully my laptop into obedience. Is there something I can configure to get osx to load correctly with my internal raid 0. I already have the correct, (and only) drive selected in start up disk, I have a Santa Rosa MBP.
