Hello! I've got 40GB of data and I need to copy it to USB hard disc drive. I'd like to encrypt it with the use of TrueCrypt so that nobody can see content of those directories, files and so on. This file is big so I guess it may require some redundant data - what if little piece of this data would be corrupted... How to create, let's say 1% of container size, to keep this redundant data? (Something similar can be done in WinZip or WinRar). Greetings!
