Hey guys, I have a 2007 mac pro running tiger currently. I'd like to upgrade to snow leopard, but I want to make sure that I'm not affecting the other drives on my computer. Currently I have all my apps on the main drive (the one that came from apple) and three other drives on the other bays. What is the best way of doing a fresh install without worrying about my other drives? I was thinking of removing the three drives, do my upgrade and then slotting the drives back in, would my computer recognize these drives? Do I even have to take these drives out? I am also going to back up my main drive via super duper. If something happens during my upgrade, how can I clone my old drive data back? Sorry for all the questions, I'm nervous when it comes this. Thanks for the help!
