If you're trying to encrypt the drive in Disk Utility, you first have to partition it with the default options, then select a volume to encrypt—not the whole drive.
How exactly do I do that? Is there any other way to encrypt it?
Is there any data on the drive now?
No I moved everything back to my hard drive because I thought that was the problem at first.
Please back up all data on the drive by copying it to another one, if you haven't already done so.
Follow the instructions on this support page under the heading
Erase and repartition a device
to partition the drive with a GUID partition map and one data volume.
This operation will remove all data from the drive.
Restore the data from the backup.
It doesn't let me click on "Partition" though.
It's and external volume, is it supposed to be an external disk?

I get this error when I try to upload the image.
You should see something like this:
Note that the drive is selected, not the volume ("Untitled") nested below it. Select "OS X Extended (Journaled, Encrypted)".
When I click on the external drive it doesn't give me the option to click partition, but it lets me click on all the others.. Is it because the drive is 2.0 and not 3.0?

No. It is because you are selecting the Volume, not the hard drive. If you are selecting the Hard Drive as Linc displayed in the screen shot, then there is something else wrong.
The volume is the only one available to click on, theres nothing else above it.

No. What happens if you click Erase?
It gives me the option to change the format, the 4 options are OS X Extended (Journaled), OS X Extended (Case sensitive, Journaled), MS-DOS (FAT), and ExFAT. It also says "Security Options" which gives the option from "Fastest" to "Most Secure".
This procedure is a diagnostic test. It makes no changes to your data.
Please triple-click anywhere in the line below on this page to select it:
diskutil list | pbcopy
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
Wait for a new line ending in a dollar sign ($) to appear below what you entered.
The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.
The Terminal window doesn't show the output. Please don't copy anything from there.
If any personal information appears in the output, anonymize before posting, but don’t remove the context.
I'm trying to encrypt a 512GB USB Flash Drive on MacBook Air OS X EL CAPITAN, However when I click on "Encrypt", create a password and then click "Encrypt Disk" I get this error "A partition, not a whole disk, is required for this operation." Help?
