Unattached disks are not encrypted

Description

Encrypting your disks protect your data from unauthorized access or tampering. That way, you can ensure that only authorized users can access and modify the contents of your disks. Such action can help protect against external threats such as hackers or malware, as well as internal threats such as accidental or unauthorized access.
