I just built a new server with some seagate 1.5TB harddisks with
mirrored
/boot and root partition , The system sometime degrade the root
partition
with error message as follow, this happened 4 times within 2 days.
It appears that model of drive is broken:

Apparently disabling the write cache is a workaround.

Heh, I wonder if there's been some firmware spying between Seagate and
Hitachi..
because my two Hitachi 750GB drives can be made to have the same problem.
Triggers quite reliably (perhaps 1/5 attempts?) by running "hddtemp"
(to read drive temperature) during heavy I/O. Bingo.
I imagine the smartmontools would have a similar effect.

Now I have to rebuild the raid everyday since every morning when I check out
the mirrored root partition, one of the drives (not always the same) fails
with the mentioned error. Strange the the 6x1.5TB raid 0 storage partition
even down because of this.
Yikes, I'll ask Seagate what's going on and post it on linux-ata wiki
when I know more.
