I am looking to create an external drive with important information and would like to encrypt this drive as well. 

I would need to have a software that would allow me to view and run files inside the encrypted partitions on a computer, regardless of my permissions level. This means that veracrypt is off the table, as a veracrypt installation is required. I'm not sure about SecurStick, I don't understand German and I don't understand whether the data is only saved on one drive or can be transferred over. 

Compatibility with Windows OS is required, preferably 2000 and up.
