Hello Tejun, I've tried with 2 sata cables. Cables which don't give problems with the Asus motherboard. I also now use a new decent power supply (corsair vx450) for the intel. Before it, i used an Fortron supply. But it had no sata connectors so i used converter adapters. But replacing the supply did'nt solve it. btw. If i copy/delete from the Western Digital to my Windows pc (via winscp or samba) i don't get error messages. Only when i write to it. The data itself seems to get corrupted; tested with par2. uploaded with winscp (windows) to the western digital (sda1). Uploaded the same data to hda1. Tested the data on both drives with par2verify. Most files on sda1 are corrupted (2 to 4 blocks missing). Copying that data back to Windows and it give the same results in Quickpar. So reading does not have problems. The data written to hda1 is correct. I now inserted a videocard, instead of using the onboard card. And at first hand it looked solved, but some (much less) errors still happens. I did not change anything in the bios. The card: 02:00.0 VGA compatible controller: nVidia Corporation NV10 [GeForce 256 SDR] (rev 10) How can a videocard influence this? I wanted to build a fileserver, using the intel motherboard. Bacause of the fact that it has a onboard videocard. I can use the asus if i have to. But if it is a bug it can better be solved :) I have some other similar motherboards like the intel laying around. With and without onboard videocard. I also have a second D815EEA (probably still has an older BIOS, i have updated the current one because when i inserted my second 128MB memory it did not gave any picture on the onboard video card). So i can do some experiments if i have to. Hope, this helps...
