Re: nForce 4 corrupting data written to HDD
I read through your input on the LKML thread, and had setup a system with the same A8N-SLI Deluxe motherboard that you're using. I've been copying a single 30GB file between two SATA disks on the nFORCE SATA controller, and running a comparison of the sha512sum of the two files after each copying iteration, and haven't run into any differences thus far. I'll let it continue to run, however I should note that we had an issue exactly like this brought to our attention several months ago and after investigation it was determined to be an SBIOS bug on that particular vendor's board (it was not Asus, however).
From your LKML post, you stated "copying certain 2 GiB files would result in at least five bytes, and as many as thirty, being corrupted every single time". Can you provide me with these 2GB files, along with details on how you were detecting the corruption? If this issue is specific to the type of data in the file(s), then I'll need you or someone else experiencing this problem to provide the files that trigger the problem.
