I've got a Seagate X15k SCSI HDD with SCA2->68pin adapter, and sometimes it used to lose power and shut off (bad contact in the adapter perhaps). FreeBSD would spit SCSI diagnostic messages onto the console about failed field-replacable unit (which I couldn't see in X Windows), restart the HDD a few times (at this point the machine would hang until HDD is restarted), and then reboot (panic?).
