Click the dotted button at the top right of the window and choose Format Disk….
Step 9: Overwrite Existing Data
Select Overwrite existing data with zeroes (Slow) from the dropdown list next to Erase: and initiate the format.
Step 10: Create Unencrypted Partition
Once the format is finished, click on the + icon to create a new partition, allocating a quarter of your disk space as unencrypted.
Step 11: Allocate Space for Hidden Volumes
Now, create a new partition using the remaining free space on the disk.
Preparing Your Hidden Shufflecake Volume
Step 12: Load Shufflecake Kernel Module
In your terminal, access your release folder and load the Shufflecake module.
Step 13: Identify Dummy Partition
Run lsblk to find the name of the intended dummy partition (for example, “/dev/sda2”).
Step 14: Initialize Shufflecake Volume
Execute the command to set up Shufflecake on your selected partition. During the prompt, input “5” to establish five hidden volumes.
Step 15: Set Passwords for Hidden Volumes
When prompted, provide the password for each hidden volume while ensuring a private environment for security.
Step 16: Create the Filesystem for Hidden Volume
To proceed, open your chosen hidden volume with the command:
Step 17: Confirm Successful Volume Access
Run lsblk to verify that Shufflecake has correctly mounted your hidden volume.
Step 18: Format the Filesystem Inside the Volume
Establish the filesystem using a command like mkfs.fat.
Step 19: Verify Filesystem Functionality
Test the functionality by creating a file or folder within your hidden volume.
Unmounting and Switching Between Hidden Volumes
Step 20: Unmount the Hidden Volume
To safely eject a Shufflecake volume, begin by unmounting it from the Ubuntu taskbar by right-clicking on the drive’s icon and selecting Unmount.
Step 21: Close Shufflecake Connection
In a new terminal, close the active connection to your disk with the designated command.
Step 22: Switch to Another Volume
To access another hidden volume, re-run sudo shufflecake open /dev/sda2 with the relevant password.
Updating Your Hidden Volume Passwords
Step 23: Modify Passwords via Terminal
Open a new terminal session and execute the password change command.
Step 24: Provide Current and New Password
Input your existing password followed by your desired new password.
Step 25: Validate New Password Functionality
Ensure that your new password is working by running the testpwd command.
