 The LBA48 should have been properly detected; is also reported a
 "id not found", and with the right address. Maybe it's a read vs write issue ?
 Could you check if a read on wd2 would trigger proper detection (obviously
 you have to remove the quirk entry first) ?
 something like
 dd if=/dev/rwd2e of=/dev/null bs=32k skip=4194302 count=5
 should do it.
