A non zero and increasing Reallocated Sector Ct and Seek Error Rate on a brand new drive is a bad sign, right ?

Just picked up 3 4TB WD drives to upgrade my ZFS mirror. I'm swapping the first drive in and it is showing errors frown

Those couldn't be caused by a dodgy connection I assume ?

They are all WD40EZRZ (I'm now regretting not picking up three different model drives like I did last time).
