How did you write zeros? I went through the archives and wasn't able to find the full smartctl -x results for this drive, can you post them? Does anyone know for sure if the ATA Secure Erase command verifies its writes? i.e. does it even have a way of knowing if there are bad sectors on a write and remove them from use? Or is the write-read verification always occurring on hard drives?
