I routinely boot from my recovery drive from start up (option key) and select the drive instead of my normal drive. I do this when I want to run diagnostics on the main drive. When I turned on FileVault, hitting the option key at startup revealed no additional drives, just the main one. I had an idea of inserting my Lion USB thumb drive that I created and it showed up and booted from there. When I attempted to run diagnostics using Disk Utility, I was unable to. The partition was "grayed" out. So, I'm a bit confused about this. Has FV deleted my Lion recovery drive? Is there no way to "repair disk" while FV is enabled?
