If a hard disk has a password set, which recovery method can’t be used?

When a hard disk has a password set, certain recovery methods become ineffective due to the security measures that are in place to protect the data. BIOS Recovery 2 is designed for system recovery at a lower level, but it is typically dependent on accessing the hard disk without restrictions. Since the hard disk is password-protected, this method cannot bypass the password, and therefore, any attempt to recover data or the system using this method would be unsuccessful.

Bootable USB recovery can be utilized as it allows the system to boot from an external device that can run recovery software capable of accessing the hard disk, provided the password is known or can be circumvented through other means. Recovery from cloud storage is also an option, as it involves accessing data that is stored online, independent of the local hard disk's encryption or passwords. Data recovery software may be able to retrieve some data if it has been previously created before the password was set or if the software has a method to interact with the password-protected disk.
