That looks like you are hitting the 128 GB LBA48 point.

note that it's the last sector.   Someplace (wd.c?) there's a quirk
table to force LBA48 for that sector.  -current now defaults to this,
I think.   Add a quirk for your drive and try a new kernel.

Before testing with raid, see if you can simply dd the whole disk to
/dev/null.
