BitLocker To Go is used to encrypt and password protect any removable external hard drives and USB flash drives. The drives must be formatted using either the exFAT, FAT16, FAT32, or NTFS file system and must be at least 128 MB. This will show you how to turn on or off BitLocker To Go to encrypt or decrypt a entire external or USB Flash drive in Windows 7.
A USB Flash with BitLocker To Go turned on for it
This is what you will see when you connect the encrypted removable USB flash drive or external hard drive to any computer. You will then need to select the option you want to use to unlock the drive to gain access.
Steps Turn On BitLocker to Encrypt Removable Drive :
NOTE : By default, Windows 7 will use AES encryption with 128-bit encryption keys and Diffuser unless changed already by you previously.
2. Connect the removable hard drive or USB flash drive.
NOTE : I will be using a USB flash drive in this tutorial as an example. If AutoPlay opens a pop-up window, then just close it.
3. Open the Start menu and click on the Computer button, then right click on the drive letter for the removable hard drive or USB flash drive and click on Turn on BitLocker. (See screenshot below)
4. Open the Control Panel (All Items view), and click on the BitLocker Drive Encryption icon.
A) Click on Turn On BitLocker for the drive letter for the removable hard drive or USB flash drive that you want to encrypt. (See screenshot below)
5. Select (check) Use a password to unlock the drive, then type in a password you want to use to unlock the drive with twice and click on the Next button. (See screenshot below)
NOTE : You can select the smart card option if you have this and want to use that instead. I just used the password option as an example in this tutorial.
WARNING : Be sure to write down this password and keep it somewhere safe. The password you enter here will be required to be entered to unlock the drive to gain access to it.
6. Click on Save the recovery key to file option. (See screenshot below)
A) Select where you want to save this file at, and click on the Save button. (See screenshot below)
B) It is highly recommended that you save this file somewhere safe, and not on the encrypted drive. You will need the recovery key number to gain access to you encrypted drive if you should forget the password, lose the smart card, or BitLocker locks the drive.
C) It is also recommended that you click on the Print the recovery key option as well to have a printed hard copy of the file to be extra safe. (See screenshot below step 6)
D) When done, click on the Next button. (See screenshot below step 6)
7. Click on the Start Encrypting button. (See screenshot below)
8. BitLocker will now start encrypting the drive. (See screenshot below)
NOTE : This may take a while to finish.
9. When finished, click on the Close button. (See screenshot below)
10. You will now have a Manage BitLocker option in the Control Panel and Computer for the encrypted drive. (See screenshots below)
11. If you click on Manage BitLocker, these will be the options that you will have below. (See screenshot below)
12. You're done. The drive is now encrypted with BitLocker To Go turned on.
NOTE : If you selected to use a Smart Card instead in OPTION ONE (step 5), then you will have that option instead here. If AutoPlay opens a pop-up window, then just close it.
