My disks are both Seagate ST3200822AS/3.01.

Okay.  I have quiet if I do nothing, and it gets chatty and then dies if I
try to move 10+GB to it from another place.  :-(

The whole point of my machine is NFS and other services.  I don't think
I even installed X.  I don't want RAID or anything extra, just disks that
work.

I saw that the sata_sii driver in the Linux kernel on one of my other
machines said there were quirks using the 3512, but I also see that the
FreeBSD driver also mentions stuff about limiting transfer size.  So
if that were the problem, it's claimed already solved.

So I'm left with deciding what to do with this machine: change OS or pray.
