I've just bought a 4T 2.5 inch Seagate external hard disk. Can anyone recommend which software is good to password protect the disk and encrypt data?
I am looking for a free software.
I use both linux and windows, so it's better if the software can work on both OS. It will be great if the software can just add an executable file to the harddisk so that I need only to execute it to unlock the disk in any OS. That means there is no need to install software in every OS.
