I have my Time Machine backups going to an external disk, and all of it is encrypted with FileVault2. I plan to do a fresh install of Mavericks on my local hard drive, but before wiping the disk, I want to make sure that I can still access my Time Machine backups.
As mentioned in this other SO post, I should be able to use my FV key (and I vaguely remember using my account username/password to access data), but I want to be 100% sure.
Short of plugging this external drive into a separate OS X box (which I don't have), what else can I do to trigger the prompt for password/FV key/etc? Would creating a new user on my machine be enough? Is there some Mavericks LiveCD mode (i.e. like Ubuntu)?
