I had bought 2 1.5T 7200rpm drives when SL came out. Originally was running one for SL and the other was just sort of hanging out. I use a TC for TM and it backs up regulary. I have a seperate MBR drive with Vista on it for occasional gaming. Also, have another bootable SL image. Well decided to try RAID0 for my SL boot drive to pickup some speed because of the beach balls I was getting during disk IO when working with videos in iMovie and FCP. It went well migrating from TM backup (as a test vice the extra image I keep) and the increased speed is noticeable. The only problem... Vista(32b) crashes soon after booting! So I booted Vista in safe mode and disabled the raided drives in device manager. Now it Vista boots just fine. I understood Vista would not "see" the raid, but did not anticipate it crashing! Any other ideas to work around the this? Regardless, just wanted to post the issue I was having with Apple Software RAID - and Vista crashing in hopes it may help someone else and what work around helped me. One other thing I noticed, when I use the option key for selecting my boot drive, I see a Snow Leopard 1 AND a Snow Leopard 2? Haven't tried to boot off the SL 2 drive... Is this normal?
