 How to enable ‘BitLocker To Go’ (for Windows) to secure USB flash drives

With the increase in the use of small, large capacity USB drives, the potential for sensitive data to be lost
or stolen has become a serious threat. How can you protect SUNY Cortland data from loss, theft, or cyber criminals while using a USB flash drive? The answer: *BitLocker.

To enable BitLocker encryption on a USB flash drive, do the following:

  1. Insert the USB flash drive into the computer, click Start, and then click Computer.
  2. Select the USB flash drive. Once selected, right-click the USB flash drive, and then click Turn On BitLocker… 
  3. On the Choose How You Want To Unlock This Drivewindows, choose Use a Password to Unlock This Drive. Once a password is entered, choose Next. 
    1. This option prompts the user for a password to unlock the drive. Passwords allow a drive to be unlocked in any location and to be shared with other people.
    2. The password should contain a mixture of letters, numbers, and special symbols.

  4. On the How Do You Want To Store Your Recovery Key window, click Save The Recovery Key To A File.
    1. In the Save BitLocker Recovery Key As dialog box, choose a save location, such as your SUNY Cortland U drive folder then click Save.
    2. You can also print the recovery key if you desire. With this recovery key file you can regain access to your encrypted USB flash drive in the event you forget your password.
    3. SUNY Cortland warns against printing recovery key information. However, if a user chooses to do so, SUNY Cortland warns to not store a printed copy of the Recovery Key with the USB flash drive in the same location. For example, if both the USB flash drive and recovery key are in the same bag during travel it would be very easy for access to be gained to the USB flash drive by an authorized user.

  5. On the Are You Ready To Encrypt This Drive window, click Start Encrypting. Do not remove the USB flash drive until the encryption process is complete. How long the encryption takes depends on the size of the drive. USB drive encryption take approximately 6 to 10 minutes per gigabyte to complete. The encryption process performs the following:
    1. Adds an autorin.inf file, the BitLocker To Go reader, and a ReadMe.txt file to the USB flash drive.
    2. Creates a virtual volume with the full contents for the drive in the remaining drive space.
    3. Encrypts the virtual volume with Advanced Encryption Standard (AES) 128-bit.

  6. Once the encryption process completes you will be notified by a window.

  2. Finally, click Unlock

 *On the Windows side, only Pro and Enterprise editions of Windows have BitLocker.  Encrypting a drive can only happen on these versions. 

However, you can unlock encrypted removable drives on any version of Windows 7 through 10. BitLocker is not available in Windows XP or Vista, but you can use the BitLocker To Go Reader to view content on BitLocker-protected removable drives from a computer running Windows XP and Vista.
