If any part of the used keyslot (which is located after visible header,
- in you case starting at sector 8 to sector 264 (hope I calculated it properly),
is modified or lost, you lost that keyslot completely.

Because you have only one active keyslot, you probably lost the whole disk:-(
(Only backup of this keyslot area can help here.)
