So I bought a Apricorn Velocity Solo x2 and simply moved my 512gb SSD OSX boot drive to it and booted up. That worked great. I've got Windows 7 64bit install on another harddrive (internal bay 4) and when I try to boot from it my system hangs with a black screen. If I move my SSD OSX drive back to bay 0 Windows boots fine. This is OSX 10.8.4. Black screen with no error messages are so fun to trouble-shoot. Any ideas?
