Which password type is specifically designed to secure an entire hard drive?

The type of password specifically designed to secure an entire hard drive is the storage or hard drive password. This password is set at the hardware level on the drive itself and is intended to provide an additional layer of security for the data stored on the hard drive. When a storage password is configured, the drive won't be accessible without entering the correct password, ensuring that unauthorized users cannot recover or access the data even if they have physical access to the drive.

This method of protection is effective for preventing theft of data; if the hard drive is removed from its original host system, the data remains securely locked and inaccessible without the correct password. This is different from other passwords, which may protect user accounts, system settings, or the boot order of devices but do not prevent access to the entire hard drive in the same way. Additionally, while a supervisor or administrator password can control access to system settings and functions, it does not directly protect the data on the hard drive itself.
