If you REALLY want to go all out on hiding it, here is what I would do.
1) get a flash drive (anything already on it will be permanently lost, so be sure it has nothing important)
2) reformat the flash drive, and enable full volume encryption. This will allow you to set a password for that flash drive. You will be unable to read or write to the drive without first inputting the password to decrypt it. (be ABSOLUTELY sure you format the correct drive, as this will destroy any existing data on the drive. If possible, remove all secondary or external drives except for the flash drive to minimize the chance of formatting the wrong one by mistake. Another way to be double sure is to put a particular unmistakable file name in the drive you want to format, then check in your file manager to identify the correct drive using that file.)
3) once the flash drive is reformatted, you should be able to use it as a secure drive for storing any sensitive information. The downside is that every time you remove the drive, you will have to re-enter the password to gain access to it again.
A few side notes: Make sure you use a password that somebody is unlikely to guess. Make it something totally arbitrary. Walk around and look at stuff until a 2 or 3 word phrase pops into your head. If its something memorable, use that. Try making at least one letter capitalized. The first letter of the second word is a pretty good choice, since its not as obvious as the first word, but still pretty easy to remember.
Second, make sure you do not forget your password. If you have chosen a strong password, there is no easy way to recover it. If you choose a sufficiently strong password, it may be almost impossible to do so. That being said, dont just have it written down on a piece of paper by your computer or something.
There are 2 things you have to defend against when choosing a password. the first is a human guessing it, and the second is a computer brute-forcing it. Its pretty easy to keep someone from guessing your password. It is much harder to stop a computer. Thats why passwords shouldnt be short. The fewer possible password combinations you have, the faster a computer can brute force it. That being said, as long as you are not worried about the NSA trying to get into this drive, you probably dont need anything too terribly secure. most people dont know how to use password cracking software, or even know it exists. Basically, dont make it very short, but you dont need to make it 39 characters with a mix of upper case, lower case, numbers, symbols, and non-english characters.
