I built my system tonight and lucky for me it booted and posted first time. It even saw my Maxtor SATA hard drive (the DiamondMax 10 everybody has been complaining about). I am POSITIVE I hooked my drive up to the set of BLACK SATA controller ports which are supposed to be the nVidia ones according to the manual. Also, according to the manual, I hooked it up to the lower right port the manual and PCB have labeled as port 1 (or SATA 1). Am I correct that this would make it the First SATA Master? Now, I was tweaking the BIOS to my liking and so I went in Advanced -> IDE Function Setup -> and I DISABLED SATA Port 3, 4. Next time I booted to try and install my OS, the drive had disappeared! So I reloaded Setup Defaults. . maybe I changed a couple things again, don't remember. After one or two reboots it was visible again. So I started trying settings one by one to see if I could isolate the particular thing making it disappear. As it turns out, I can reproduce the problem 100% every time by disabling SATA Port 3, 4. If I re-enable the ports 3, 4 then the drive shows up even if I disable Ports 1, 2. Isn't that interesting? And I am looking inside the case right now and I am SURE it is hooked up to the port labeled as 1 on the nVidia SATA controller ports! It's like they labeled them upside down or flipflopped them in the BIOS or something! Can anybody else who is having trouble with Maxtor drives verify this?
