Choose the partition or disk that you want to encrypt. We will choose /dev/sdb in our example, as it is our secondary hard drive. This is just a raw block device, with no partitions of file system currently installed.
👁 Choose the hard disk partition that you wish to encrypt Choose the hard disk partition that you wish to encrypt
As long as you are sure that you have selected the correct device, choose yes on the next confirmation prompt.
👁 Click Yes to continue Click Yes to continue
Enter your adminiatrator password, as you need root permission to perform the next step.
👁 Enter root password credentials Enter root password credentials
