I realize this is an old thread, but the EOD encountered by the OP is from partition 0, not partition 1, so it is not the case of the data partition having an EOD mark at byte 0. dd was encountering the index partition EOD, and so the question of how to advance dd past that marker to the data partition is still on the table. Unless you meant that the LTO consortium locked out going beyond the EOD for the index partition, which is not what you said.
Could you clarify or explain what I may be misunderstanding?

Thanks.
