Is that correct ? It seems that you have the ata2 port that is connected not to a disk, but to another disk controller. Robert Ancock wrote me : "There is something connected, I believe what's actually there on this board on that port is the SiI4723 chip which is connected to two other SATA ports. For whatever reason it gets detected as a drive, and it also seems to be not responding until we do a few resets.. http://www.siliconimage.com/products/product.aspx?id=64" regarding my P5W DH Deluxe motherboard. To date, I still don't have any solution for that problem... but it seems you have some advance as you wrote : "If I turn off AHCI then it seems to be okay." I need to test this on my machine too...
