Hello, As per TrueCrypts documentation and other tutorials online, I cannot decrypt non-system TrueCrypt partition on the fly. Now if I encrypt my entire 500 GB external HDD it'll be very difficult to move data that to another 500 GB storage device, if in case in future I want to remove the encryption. In this case is it possible to install linux or any other small OS on my external HDD to fool truecrypt to believe that it is a system partition as well and hence decrypt on the fly?? What do you think? Also if TC can decrypt system partitions on the fly then why not add the same feature for non-system partitions/file containers?? Strange!!
