Freezing ATA Security

unlockata can freeze the current ATA Security configuration using the -op freeze operation.

Freezing ATA Security prevents security-related commands such as setting, changing, or disabling the password until the next system reboot or drive power cycle.

sudo unlockata -device /dev/sdb -op freeze

Or using the drive's serial number:

sudo unlockata -serial 2021030400273 -op freeze

If successful, unlockata should not report an error.

Note

ATA Security freeze is typically used to prevent software running after boot from modifying the drive's security configuration. The frozen state is cleared after a reboot or power cycle.
