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. Software is preferred but I'll work with hardware if need be.
