Actually, I would go with the "it's an operating system error." That's exactly the same error quite a few people (myself included) have been reporting under 5.4 and 5-STABLE. In my case, I just installed the smartmontools port and it's reporting that my drive is behaving perfectly. This is 6.0-Beta? I have a couple spare drives here (destined to be part of a RAID array on another machine). Perhaps after I get rid of some of the current RL overloads, I will try it on this machine.
