This might sound like an odd question, but please hear me out. I want to setup my laptop to use TrueCrypt, but without a password. My wife doesn't travel much with her notebook. There are occasions where we will have to travel and bring the notebook with us. This is when we would like the have the encryption.
The time it takes to to change the unlock pass-phrase is considerably less than it takes to encrypt the drive. My thoughts are to leave the disk encrypted but with no password. Then when it's time to pack for a trip and bring the laptop, we would then change the pass-phrase and create a rescue disk.
