I will show you how to make a super, unhackable USB drive. It will be of no use to anyone but you, and even if someone had access to government grade hacking software, they would not be able to access the data.
I am NOT responsible for whatever you put on the drive, or whatever damage you do with said data or the drive.
Step 1: The Tools
1) A USB drive
The USB drive can be obtained at any store that sells material items. You should probably get a 1GB or bigger, because 1GB only costs about $10. I am using a 4GB that I have had for 2 years (same as the one in the picture below, just half the memory).
TrueCrypt is an open-source (free for your not-so-computer-knowledgeable-person) software. It uses government grade encryption (256-bit) and better, so you can be sure your data is safe. You can download it at http://www.truecrypt.org/. After installing it, you will need to restart your computer.
