Duncan,

I never get those high temperatures here, the highest I've seen at home
is ~30 C (86 F), no AC. I don't think the failure is temperature
related, I always mount a 12cm fan in front of the the HD enclosure, and
the HDs aren't even warm.

Previously the same HD was mounted in a different box, still AUSUS mobo
but VIA chipset instead of NVidia, and different BIOS. In that box the
disk was not automounted from fstab and if not mounted manually it was
normally completely cold even without the 12cm fan running, so I suspect
it was not even spinning (low power mode from BIOS?). I mounted it only
to archive movies after viewing them. In the Nvidia box behavior is
different, the disk warms up even if not mounted, but with the 12cm fan
always running the temp is low.

I have no explanation for this failure. The disk was used really little.
After (if) I recover data I'll try to read the HD SMART database, if I
remember well there are some useful counters there.

The HD is less than 3 years old and should still be under warranty, I'll
 try to get a replacement from Seagate. But my movies are more important
now!

I'm sure it's not related, but the irony is that just few hours before
the failure I had run an e2fsck on that partition, not an error did it
report.

PS Thanks for the hint on block size.
