Encrypt your Drive using SanDisk SecureAccess 3.0
As I prefere to use services for all kind of users I decided to buy a comercial USB Drive on Walmart and use the brand software for encryption. It was very easy to install and use because the user interface, it ask me for a "secure" password +8digit, special character, lower and upper case, numbers. After the encryption my drive has and special "folder" when I can store files and access them by the interface. It has the application portable so I can access them on any Windows/MacOS device.
