Typically, the flash drive will be given any letter after the letter "D:" ("E:", "F:" or "G:") depending on how many drives you already have installed on your computer.


Open up your disk encryption software. When the software prompts you to select a drive to encrypt, enter the drive that is allocated for the flash drive ("E:", "F:", "G:").
