Then something on your system is defective. Normally the BIOS
initializes and unlocks the drive.

It could be worked around in clonezilla with a custom built CD and
some script that unlocks/resets/whatever the drive but at the point
the drive is locked the firmware in the drive might be completely
locked up requiring full power cycle to respond to any commands.

It might be that Linux triggers some bug in your drive's firmware
which has happened in the past with some drive models.

I don't think this is a clonezilla specific issue, though.
