[ Thanks to Ramsai

“In this tutorial by Christer Edwards, we will look at
steps toward encrypting removable media such as USB thumb drives
for secure management of personal data. This tutorial will walk the
reader through seven steps required toward identifying, formatting
and encrypting a removable disk for use as a secure partition.

“The other day my Dad mentioned that “any true geek always
carries a USB drive with him”. I proved my geek-hood by producing
the 2G titanium thumb drive from around my neck. I then did him one
further by telling him that the drive was encrypted with AES 256
bit encryption. I don’t know whether or not he was impressed, but I
sure proved that I am a true geek. It was this experience that
prompted me to share my instructions on how to securely encrypt any
removable drive.

“Following the steps outlined in this tutorial will wipe all
data from the device / partition that you present to the encryption
utility. You cannot encrypt an existing system using this method
and retain the data. Please ensure that you have backups of your
data, or that your data is otherwise expendable.”
