The standards are very explicit about what READ CAPACITY(10) should
return for a >2TB device.  sd detects this and retries with a READ
CAPACITY(16).

There is no message in the log indicating this happened, so I think the
device reported an incorrect size to READ CAPACITY(10).  It may have
reported its size with bit 33 lopped off, but that's still a device
problem.
