New WD6400AAKS not detected in bios, but in Ubuntu

I just bought a new WD6400AAKS sata hard drive. I have 2 other sata hard drives on my Asus a8n-e motherboard, nvidia based. I have set the nvidia raid setup to spanning in the utility, via f10 setup utility. I previously had 2 raptors in RAID0.

The problem is that that nvidia utility detects the model number and everything about the drive, but the bios does not. But I was able to install ubuntu, detected the drive, but upon reboot I got the NTLDR is missing error. Windows was installed on the RAID0 previously, but I don't think that would stop it now because Grub would be put in place when Ubuntu is installed.

I read online that some via and sis chipsets had problems detecting sataII drives on sataI motherboards. So I thought it could be a problem, still no luck.

I am pretty technical but for the life of me I don't know why this one is stumping me. The only thing I can think of is that I need a bios update, but after searching I could not find anything linking this new drive to a bios issue, the bios is revision 1010. Like most people now days I don't have a floppy drive and from what I remember bios' could only be updated via floppy, first to admit I'm wrong about that one.

If I have not given enough information let me know so I can help you, help me.

Any advice will be well appreciated.
Thanks, Dan.

If the bios doesnt detect the drive it is most likely ubuntu wont boot off the hdd since it will only boot from hdd that exist.

You can change the jumper on the phyiscal hdd to SATAI the top of the Disk should demonstrate how.

try changeing the sata port too and removing the others

Sometimes there are two sata chipsets on board
the secondary show up as a generic device name (SILDisk etc) not WD6400 in bios

Thanks for the help. I was messing with the jumpers on the hard drive and unplugging the drives all night. But then I saw that the first 2 sata ports were not detecting any drives. I had to disable nvRAID in the bios, now it detects all the drives in the bios. Thanks again, hope this helps someone else coming off a raid setup.
