I just added a new drive to the chain (ST410800W), and started to get
the following errors:

The error pops up at random intervals. Just now, I'm beating on the
drive with dd, and only 6 (the last 6 of above) errors popped up. All
the other showed up during the booting process.
I tried to fsck the filesystems, but it checks out all right. sd0 was
working perfectly before the upgrade, has never produced any error
message since the whole system was put together one year ago. sd1 is
connected to the narrow cable in an enclosure a wide-to-narrow adapter.
Does anyone have any idea on what's the problem?
Here's my dmesg:
