I fully agree!

Maybe "Skip" would be more precise than "Cancel"?

Also I think "erasing" doesn't quite hit the mark because it leads
users to believe that the step isn't necessary for a new drive or if
they don't care about securely deleting its previous contents. How
about something along the lines of: "Overwriting ${DEVICE} with random
data to prevent meta-information leaks from the encrypted volume. This
step may be skipped at the expense of a slight reduction of the
quality of the encryption."

I can back this up with my own experience.
