I have an issue from the first day I installed 10.8, if I start the system with only 1 HD, there is no problems, but if I connect a second HD, then, only sometimes, the boot fails, I don't see any message, only the white apple screen freeze, or the login screen freeze. Sometimes the mouse moves very very slow, and I need to reset.
I have a SSD for system, other for free spaces and time machine, and now I bought another for Windows, when I connect the 3 Harddrives the problem is worse.
I don't understand what happen.
Can give some light? Thanks
