    I have similar problem, the disk is not frozen but for all -security-* commands produce Input/output error.

    As my motherboard is gone the freaking disklock password is gone too (randomized by bios) and there is
    no way to unlock the data but i would at least like to rescue the disk by wiping it. It is known that security
    wipe resets the password but i always get this error. (yes i have set the temporary password but even on
    that i get the same error).
