This drive is the exact same model that Alex Petrov also had problems with: ada1 at ahcich2 bus 0 scbus2 target 0 lun 0 ada1: ATA8-ACS SATA 2.x device ada1: Serial Number S0MUJ1KP317818 ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada1: Command Queueing enabled ada1: 476938MB (976771055 512 byte sectors) It claims to support Read Log, but actually doesn't. The change I checked in in revision 300640 will only send a Read Log (and additional SMR probe steps) to drives that claim they're SMR drives. Any non-SMR drives should get the same probe as before.
