Since my T410 has encrypted drive with LUKS, I started to try to encrypt a 120GB USB drive. It’s very easy. Just plug the USB drive and launch the Disk Utility, then you can format it with encryption.
But I don’t want it ask me password every time when I plug it in, just select “Remember Forever” when input the password.
