Picture of How to Secure Your USB Drive
Everyone has files they don't want others seeing. Maybe they are financial documents, school work, or other "questionable" files. Whatever they are, you want a way to secure them. Putting a password on your PC will do you no good, and it would not be portable. Buying a USB drive makes data portable, put usually not secure. For truly secure data, you need an encrypted USB drive.

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

Picture of The Tools
First and foremost, you need two things:

1) A USB drive
2) TrueCrypt

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.

A secret -------------> there is only one known sure fire way of getting around a content filter.

Use DDNS for your own PC. Setup a proxy on your PC. Make sure you know the port its running on.and the hostname.(DONT SHARE IT, trying to make it look like you are a guru) Major usage will get you unwanted attention, and ANYTHING that happens, even things like bomb threats, will be traced back to YOU. You can actually use a VPN or proxy on your own box at home, connect to it, and you are usually ok. Me personally, I knew this would happen so I stopped it before it got started, but most school admins are uselss in I.T. security. As for the usb drive, there is nothing that cannot be invaded, dont get over confident.

Sorry, man, but this is simply not the way to hide.

You people really think that is UN-hackable? Seriously? Who writes this stuff? I came here to see if someone had really done that. But nope. The government WILL NOT ALLOW ANYONE TO MAKE SOMETHING they cannot bypass, backdoor, etc.....I myself wrote a script to deal with this in under 3 seconds, gave me full remote access, changed permissions, gave me silent, invisible remote access, and set flash drives file system to ntfs, all in one boom, gotcha. I could copy the data somewhere, destroy it, or keep the USER HIMSELF from ever touching that data again without my say-so. I was the Senior Systems Admin for a county wide school system. Best thing to do is, kiddos, read your books, lessons, whatever. Or you'll run into someone like me, who will make you come crawling to my office to unlock your data.

TrueCrypt is no longer available for official download. You may want to consider using EncryptStick (www.encryptstick.com) or SecureAccess (http://www.sandisk.com/products/software/secureaccess/ ) instead.

Truecrypt can be accessed by the government. Here is a presentation of a law enforcement agency saying they can get inside Truecrypt as well as MS Bitlocker.


@echo off

title Folder Locker

IF EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B303­­09D}" GOTO UNLOCK


echo Folder Created.


echo Are you sure you want to lock the folder? (Y/N)

set/p "cho="


IF %cho%==y GOTO LOCK

IF %cho%==N GOTO END

IF %cho%==n GOTO END

echo Invalid Choice.



ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B303­­09D}"

attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B303­­09D}"

md Locker

echo Folder created.



This one works for me... I just converted the bat files to exe.

Just download the converter here..

USB encryption is must these days. Person like myself, I carry sensitive information around and most of the times I forget my USB here and there. Obviously I would not like my friends or anyone else to peek in. That is the reason I use encryption and I partcularly use Data Protecto. The software has been good to me. Its been 3 years now and i have been using this software. I am glad i tried it. Recommend too. http://www.dataprotecto.com/

It's a good idea to password protect USB by truecrypt before its holes published. Now bitlocker or this folder protector: http://www.kakasoft.com/folder-protect/ which is easy but safety is good choice.

This is a really cool idea. BUT, my problem is that where you put "A hidden partition gives you what is called "plausable deniability." This means that there is a hidden drive there, and someone may know it, but they cannot prove it. A hidden partition is a great place to put REALLY sensitive documents." made me immediately think that paedophiles and internet perves could use this to hide paedophilic files and images. Does anybody think the same?
No, but I am now - thanks for blabbing - now I am sure that you have given the idea to those exact people that might be reading this.
Sometimes it's better not to say anything.
Good point... Didn't think about being 13 at the time.
Its very important to protect USB drive as its one of the most vulnerable part of computer. The software recommended above is really good, but along with that i also use the techniques given here " http://techwikasta.com/2012/10/how-to-secure-your-usb-drive/ " , this help me keep my USB drive more secured.
what is the gutmann method? please tell me
It is a method of data deletion where the data is overwritten 35 times. If you delete files using it, they will be impossible to recover.
will it deleat everything even if im entering my really really long password and i tap a wrong key.
TrueCrypt is good for encrypting documents and securing them but it is hackable.
I've done it before because I accidently forgot my password for it.
Crazy Leprecaun (author)  Jamez Britton4 years ago
And how'd you do that? Because it's government-grade encryption.
i downloaded a government-grade password variable hacker
Crazy Leprecaun (author)  Jamez Britton4 years ago
Oh really? And where'd you get that?
IAMAFISH5 years ago
Thanks for the instructable it has been very useful. What if your a paranoid terrorist government agent instead of just one of them?
I'm rolling around on the floor laughing at the above right now...
jvpernis5 years ago
can you make an usb which encrypts all files on the hard drive (and really secret files stored on the usb) until the usb is plugged in? and if u pull out the usb that all files will encrypt automaticly again? that'd be awesome because it is kinda like a key to your computer. very useful when u have a laptop. nice instructable by the way!

A good starter tutorial, but Step 4 in your article is not always correct. I'm purely writing this to be informative, not to insult you. Flash drives use flash memory to store data, which tends to wear down after a prolonged usage. To prevent it from wearing down as quick, a technique called 'wear leveling' was implemented. Instead of a physical sector of the drive being overwritten like a normal disk, new data gets written to unused sectors of memory, while the 'overwritten data' just becomes free to use. Basically, there's two problems you'll have. The first is you won't actually be overwriting the old data, it will just write off to unused sectors to prevent wearing. Second is you're using the Gutmann method to make 35 passes across unused sectors that may never overwrite the old data, also causing wearing to your flash drive.

Hi I'm on a Mac and when I attempt to encrypt my flash drive it asks me for a pass word and when I enter a password it says incorrect. Any help?

Can i apply this method to say, an entire internal hard drive in a computer?
bsoud5 years ago
I have an external drive for work. Its encrypted and I was able to mount the drive at work. However, when I try to auto mount it at home, i put in the password, and it says "Incorrect password or no TrueCrypt volume found"...I Absolutely have the right password, its the one I used at work. Any ideas?
mox386 bsoud5 years ago
I have the same problem, and there seems to be nothing out there on the internet about the Truecrypt "Incorrect password or no TrueCrypt volume found" error on the automount feature of truecrypt. It's getting to be a real hassle as it used to work on this computer. You can kinda tell others are having the issue, but there are no answers out there yet, and I've been searching for a few months off and on.
Crazy Leprecaun (author)  bsoud5 years ago
The obvious answer would be that you are selecting the wrong drive to decrypt. If that's not the answer, try one of these:

1) You did forget the password (or a keyfile).
2) The header is corrupted.
3) Some strange OS or user privileges issues.

If none of those work, try the TrueCrypt Forums or TrueCrypt FAQ.
 It says resource busy whenever I enter the password.
 Hi, on a mac, I see a select device button at the bottom of the screen, do I need to worry about this section?
 On second thought, never mind, my new question is it asks me my volume location and to select file.
 Can I add documents as I save them without reformatting?
Crazy Leprecaun (author)  M4industries5 years ago
Yes. You just add them when the volume is decrypted, then dismount the volume when you are done.
and the retartard states he is a terriost govenment agent and paranoid. well i say good luck with that. and good work on the instructable i put it on my flash and it works exept the fact that when i go to use it my computer says insert a drive into the port.
Yeah, it will do that. You can't access the encrypted drive from My Computer (or your OS specific file browser). You have to use TrueCrypt to access it in it's "decrypted form".
can the drive be mounted without the truecrypt software installed on the computer you are using?
Crazy Leprecaun (author)  Psychic Master6 years ago
No. You have to have TrueCrypt installed on the computer. HOWEVER, if you have administrator privileges, you can use TrueCrypt in traveler mode. See the website for details.

How would we put are computer password as the truecrypt encryption is that possible
Crazy Leprecaun (author)  rada1946 years ago
Sorry, but I can't understand your question.
