Looking on messages, I would say that you are using AHCI controller with old ata(4) driver. I would recommend you to try new ahci(4) driver. It has better hot-plug support and also supports NCQ and some other features. Note that disks connected to it will be reported as adaX instead of adY. -- Alexander Motin
