I formatted one partition on my external drive as MacOS Extended (Journaled, Encrypted).
Now when I open Time Machine and want to use that partition I see a checkbox Encrypt backups.
Because I don't want to encrypt my backups twice I unticked this checkbox. But when I continue Time Machine asks me for the password of this partition to be able to turn off the encryption.
I do not want to turn it off.
How can I use already encrypted disk?
