This device works well on Windows 7 if HDD is already partitioned. Sounds like Win7 gnores the READ_CAPACITY value on a partitioned HDD. It shows 4TB on disk manager, but will fall back to 1.8TB if I remove the partition.
Could we do the same? Would be possible to signalize to upper layers that capacity is not accurate (or return zero) on this device, and tell GPT handlers to bypass it's partition_size vs disk size consistency check?

Thanks,
Alfredo
