Traveling with data has always made me nervous because of the possibility of losing my thumb drive … with passwords, FTP info, POP3 email (still working on a solution for that one), etc. This same problem transcends my thumb drive (no pun intended) … the laptop is also a major problem.
The one downside is that the volume will not grow based on the amount of data inside. When you create the volume, you need to specify how much memory you want the volume to have.
Once you create the volume, unmount like you would any external drive (like a thumb drive for instance). The next time you mount the drive via True Crypt or Portable True Crypt, enter the password and you have access to your files again.
The recommendation for a more secure password includes letters (upper and lowercase), numbers, and symbols totaling at least 20 characters.
At this point in time, I believe this is Linux and Windows only. For our Mac users, you can accomplish the same thing using Disk Utility or can opt to encrypt the entire drive.
Until next time …
