Hmm... that's interesting. >> This new motherboard has an onboard Sil 3112 as well. The old onboard >> was VIA SATA, which did not corrupt anything.

Some drives have a jumper that lets you > limit their operation to 1.5, which you could try. 3112 doesn't to 3.0 Gbps and SATA auto-negotiates transfer speed when PHY goes online. The jumper helps detection on some dump controllers but shouldn't cause data corruption. >> 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?
