Make a Hidden and Encrypted Hard-Drive Partition for Free

This is how to make a partition, like the C: or D: drives that are already on a new computer, but it is hidden to everyone (does not show up on my computer or anything like that) and has Government-grade encryption, and all for free. It will require some basic computer knowledge and some time; as a rough guide 10 GB took about half an hour but the larger the partition the longer it takes.

Step 1: What You Will Need

For this you will need:
A computer with a working OS and the Internet
Truecrypt you can download this for free from here
A memory stick or other removable storage device (optional)

Step 2: Create the Partition (Windows)

To create the partition in windows first run the program "diskmgmt.msc" (without quotes) as an administrator it should come up with a window like Picture 1. Then you need to right click on your C:\ drive and "shrink" it by however big you want you hidden partition to be; after a few minutes it should look like Picture 2. Then right click on the unallocated space and select "New Simple Volume" and go through the menu (it doesn't really matter what drive letter or file system you choose) and then wait while it formats your drive; it will then look like Picture 3. Now right click on the drive you just made and select "Change Drive Letter And Paths" then select whichever drive letter your drive is formated as and then click "remove". It should now be named "Raw Logical Drive" and should say however big you made it; it will look like picture 4. I am still working on other Operating Systems but as soon as I get a step by step for them I will update this Instructable

Step 3: Encrypt the Partition

I am assuming truecrypt works the same on all operating systems but if it doesn't please tell me and I will change this instructable accordingly. Firstly open truecrypt (on vista you might need administrative privileges). Now follow the image notes.
