I upgraded from XP Pro to Win7 Ultimate using a clean install. My computer box has 2 Sata 3.0 internal hard drives. I used to be able to switch power on to the second drive and XP would recognize it and then I would have access to it. After installing W7, I can no longer do that. If I reboot and switch power on before it boots, then I do have access. This is one of those things that is not critical, but is just irritating. Any ideas?
