I think these drives are just kinda broken :( I noticed we had the 2TB versions of this line, but they seem rather different and I am not able to trigger the errors with them thankfully. Even stranger, I have a 1TB version of this drive I bought from a while back that has the same firmware, but does NOT have this issue. However, the output of the identifier is slightly different. Who knows, it could be some component WD uses that *should be* the same but is not and is causing some subtle pathology. I tried turning off NCQ on the controller and it didnt seem to make a difference. Then I turned off autotrim and did a manual trim of the pool, then did the tests and same sorts of errors. I think I am just gonna cut my losses with these disks :( Even if I figured out some work around at this point, I would not deploy them into production. I doubt I will be able to get anywhere with WD. Farewell my 400 bucks :( (da6:mpr0:0:16:0): READ(10).
