adding truecrypt hidden volume to already existing volume

[jack daniels]

hi,
i've full disk/system encrypted my linux xubuntu through native encryption setup when installing. i'd now like to add to this an outer volume, making my current one hidden. i'd also like to boot the less-hidden volume run XP.

is this possible without wiping the entire harddrive again? the standard option in truecrypt seems to be to create a fresh outer volume first (ie. the not-secure) and put the 2nd inside it (the one i already got, and want hidden).

thank you, any help would help a lot!

It will need to be wiped. And don't use the hidden volume wizard, you need to use the hidden operating system wizard, otherwise you won't be able to boot the hidden system.

thanks rabbit..
but - is there no way to create - i mean, the volume, the whole shebang is atm encrypted. there is no way to split it up, so to speak, and create a second encrypted os alongside the existing one? i'm sorry if i'm repeating myself, but it's just i spent three days finding all my dependencies......

i'm also curious as to what the encryption scheme in xubuntu is compared to truecrypt? is it actually the same, or some native xubuntu setup?

thanks again!

There's no way. The outer volume must always be created first. Only then can it scan the disk space to create a hidden volume.

It probably uses AES by default but it can support other algorithms such as Twofish and DES.

ok, thanks a lot rabbit!
much obliged.
