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). > This new motherboard has an onboard Sil 3112 as well. The old onboard > was VIA SATA, which did not corrupt anything. The Sil 3112 onboard now > does too. 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. > Scipt used to md5sum to find corruption: > > find $* -type f -print0 | sort -z | xargs -0 md5sum 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. -jim - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
