Encrypt a USB Drive

28 Apr, 2023

sudo apt-get install cryptsetup
sudo lsblk
umount /media/james/Extreme\ Pro 
sudo dd if=/dev/urandom of=/dev/sda1 bs=1M count=100
sudo cryptsetup --verbose --verify-passphrase luksFormat /dev/sda
sudo cryptsetup luksOpen /dev/sda sda
sudo mkfs.ext4 -L EncryptedWD4TB /dev/mapper/sda 
sudo cryptsetup luksClose sda

Then I safely remove drive in Nautilus, unplug and plug in the drive.

I'm prompted for my password.

Finally to make the root writable I change its owner:

sudo chown james:james /media/james/EncryptedWD4TB
