Almost every computer user today has at least one USB flash drive. These handy storage devices are often found in pockets or used as keychains. Unfortunately, their small size makes them easy to misplace or lose.

When you lose your USB drive, there’s always a risk of someone finding it and going through your personal files. So, to truly protect your data, make sure your USB flash drive is secure.

You can easily do this with your Mac computer, which allows you to put a protective password on your data. To do so, you can use your Mac to create an encrypted disk image of your USB drive; the disk image becomes a container for your data and only authorized users who know the password can open it.

Tutorial: How To Encrypt A Flash Drive In Mac:

There are many ways to encrypt USB Flash Drive in Mac, also you can use many tools to encrypt your files or full disk, but in this tutorial, we are going to use Mac Internal Encryption program which is highly recommended.

Another method: We are creating another folder inside your USB drive which is encrypted and contain your sensitive data in it. This is the best way because you don’t need to enter the passcode each time when you are accessing the files other than the Encrypted Folder.

  1. Insert your flash drive into a USB port on your Mac. Copy all files on the drive and paste them into your Desktop. The USB drive has to be empty during the encryption process. All files can simply be copied back onto it after the completion of the encryption process.
  2. Once the flash drive is empty, open Disk Utility, which is found under Applications in your Finder menu.
  3. You will see a window with a list of devices towards the left portion of it. Choose your flash drive from the list.
  4. Go to the Erase tab and click on Format to open the corresponding menu. From the choices, choose Mac OS Extended (Journaled). You will be asked for a name, which you can freely choose.
  1. Click on the Erase button at the bottom of the window to delete all data on the drive. Wait for the process to be completed.
  2. After the process, open the File menu and click on New, then tap on Blank Disk Image.
  3. Save Location should be your USB Drive Name.
  4. Choose the size closest to the full capacity of your USB drive; make sure the size is smaller. As for the Encryption menu, choose either 128-bit or 256-bit AES encryption. As for the Partitions, choose Single Partition.
  5. Go to Image Format and click on Read/write disk image. Finally, click Create.
  6. A small window will appear where you will be asked to provide a password. Don’t lose your password as you will not be able to access your data without password.
  7. Paste all your old files onto the drive; place them on the DMG disk image file. If you don’t save them in that file, they will not be password protected.

Tutorial: How To Encrypt A Flash Drive In Windows:

Windows 7 and above versions have an internal feature called BitLocker, which is used to encrypt internal and external drives. Unfortunately, Password protection is not available as a built-in feature in Windows XP, 7, 8 or even in 10. But there are few third-party tools available for password protection.

There is another tool called “TrueCrypt” which is now moved to BitLocker, was previously used for the same purposes.

How To Encrypt A Folder In Flash Drive:

In this tutorial, you will see how you can encrypt particular folder inside your Flash drive. This is the best way to encrypt and protect your Folder data, it’s also best because; you don’t need to insert the password each time you want to access other files on your USB.

Unfortunately, there is no built-in feature available for Windows users for that specific task. But you can use third party tools like Lacie Free Encrypted Tool to Encrypt your Folder.

Here Are The Simple Steps to Encrypt Folder In Flash Drive:

STEP #1:

You need to download ZIP Files From Lacie website. Download and extract the files.

STEP #2:

Copy All Extracted Folders and paste into your USB Flash Drive.

Remember “this folder should be copied and pasted into root, it shouldn’t be inside any subfolder, otherwise it won’t work”

STEP #3:

Paste all the Extracted Folder inside your USB Flash Drive.

STEP #4:

Go to the extracted Folder and find the private-public.exe file and run it.

STEP #5:

This is where you can give a size to your folder, in my case i’m just using 500mb for demonstration. After giving the size of your folder simply click on “Next”

STEP #6:

Now Create a password for that folder: choose the password and click next.

STEP #7:

Hit Next and process will start in few seconds, it also depends on your data and PC performance, usually it takes 1 minute per 1 GB transfer.

STEP #8:

When it’s done, it will take you to disk mounting process. Here, you just need to put your created password in the fields.

STEP #9:

It’s almost completed, if you go to “my computer” you can see there are some other drive pop-ups! which you have created. Put all the sensitive data in it and it will automatically save into encrypted folder inside Flash Drive.

Now all of your data in that encrypted drive is protected through encryption and once you disconnect the USB Flash drive, the encrypted drive will go away from sidebar or in “My Computer”.

When you reconnect your Flash Drive, it will not going show you the encrypted folder which you have created, because it’s hidden. In order to retrieve that you need to go to your USB storage and again run the private-public.exe, and this time it will just ask for a password.

Once you provide the password, that will drive show again and you can check your data inside.

Are There Any Risks Of Encrypting Flash Drive?

When we think about encryption, it always seems beneficial which is mostly true. However, in encrypting a flash drive, there are some issues to which a user is still prone.

The password could be the greatest issue as the whole encryption process depends on keeping a strong password. If your password is easy to guess or doesn’t contain strong characters then there are chances that it could be revealed.

Most people write down the password to remember it which produces the chances of losing it. Also, if the encrypted flash drive is entered into a compromised device with key logging software then you may lose the password while entering it.

However, the most probable risk is the loss of the password if you forget it and there is no chance to decrypt USB data without password. But, there are the ways to recover password such as BitLocker’s recovery key or a clue or to store it securely.

  1. VeraCrypt is a alternative to use for encryption with up to 15 different types of encryption options. Use for entire systems, entire drives, USB drives and single type folder container.

    Not sure what you mean by this statement: “There is another tool called “TrueCrypt” which is now moved to BitLocker, was previously used for the same purposes.”

    Actually, Veracrypt has taken over the place of TrueCrypt. I use it quite often. I like the fact that a type of double encryption can be used so that if someone tries to force you to give them the password, you can, because another volume/container is hidden within the first with another password.
