Just about any self respecting geek always has a flash drive handy. Whether it is on your key ring on in your purse, having the ability to access certain files and utilities anywhere can really come in handy at times. However, if you were to lose or have this flash drive stolen, depending on what is stored on the drive, you could be setting yourself up for a completely preventable disaster.
With the help of TrueCrypt, you can easily protect the data stored your flash drive so that if it is lost or stolen, nobody will be able to get to your sensitive files.
Creating a TrueCrypt Volume
Plug in the flash drive you want to protect data on copy any data you want to protect onto a folder on your hard disk. We will move them to the encrypted volume once we are done.
The process of creating an encrypted file container for a flash drive is no different from the normal TrueCrypt process. If you are familiar with how to do this already, you can skip this section or just scroll through it for a quick refresher.
From the Tools menu, select Volume Creation Wizard.
Select the option to Create an encrypted file container.
We do not want to select the option to encrypt a non-system partition/drive because this would prevent us from loading the files required to mount a TrueCrypt volume on our flash drive. This would mean the computer we plug our flash drive into would have to already have TrueCrypt installed in order to access our data.
Select the option to create a Standard TrueCrypt volume.
Set the destination to a file located on your flash drive.
Set your encryption options. The default values will do nicely.
Set the size for the encrypted volume. Make sure you leave at least 10 MB free so there is room for the TrueCrypt files required for mounting and dismounting the volume.
Set a strong password.
Wait patiently while the TrueCrypt volume is created.
