Hello, I recently installed an intel 40GB SSD and have replaced my optical drive with a caddy for my old hard drive (as I almost never need it, and when I do need it, an external works fine) and when I try to rename one of them, I cannot boot the SSD. The old HDD still has OSX on it and can intermittently boot when one is changed. When I change one or more, the error I get when booting the SSD is that my user profile (the only present on the disk) cannot be found to log in. Does anyone have any experience with this? i gave the SSD a rather poorly thought out name, and would like to change it.
