OK Sorry. I assumed the bridge is smart enough to do nothing,

ie READ_CAPACITY_10 is passed as is via sata to the device that
actually supports READ_CAPACITY_16, as I understand then the 
actual good drive is not suppose to send size-modulue-2G in
response to READ_CAPACITY_10. Should it ?

Then the bridge just sends that back to me, now if I send
READ_CAPACITY_16 the bridge will return NOT-SUPPORTED because
it is unexpected.

But what are you saying that the bridge was smart enough to
do READ_CAPACITY_16 get a 64bit value from the drive and then
return the lower 32bit to me ? Really ? I would not imagine
in the life of me someone so dumb. And surly it is against
any spec.

Are you sure ? I think you are wrong I think the guy reported
that he can only see 2T out of his 3T drive which means the
bridge returned 0xffffffff, exactly 2T

But hey, I guess stupidity is limitless, this one here pushing
real far.
