Have you tried different disks?  I recently spent a long time trying
to track down the same sort of problem and it ended up being a bad
HD (not a media failure, so SMART didn't report it).

Maybe the VIA controller was only 1.5 Gbps and your 3112 controllers
are running at 3.0 Gbps?  Some drives have a jumper that lets you
limit their operation to 1.5, which you could try.

Can you figure out the nature of the corruption?  Flipped bit, entire
blocks corrupted, etc?  Maybe make two big identical files and use
"cmp -l" to see how they read differently.
