I have an XFX nForce 680iLT motherboard with 8 gig. I have installed two optical drives, a TDK IDE CD/DVD burner and a new Asus BW-12B1ST Blu-RAy Writer. I also have three hard drives, two IDE and Three SATA hard drives. The power supply has been upgraded to a 750 watt OCZ Fata1ty
When I boot up the computer, the BIOS shows all my drives.
My Win7 ProOS does not recognize the two optical drives and one SATA drive.
I moved the SATA drives to different locations to see if that changed anything.
In Device Manager the SATA ASUS and the TDK CD/DVD drives show up with the yellow error exclamation saying that the drivers cannot be found bur when I check the properties is says the drivers are correct for the device.
There is also a yellow error icon for an "Unrecognizable Device"
I have deleted the three error enties but when sestarting I get the error message that the correct driver cannot be found.
I cannot find a new driver on either the ASUS or TDK websites but I think it is a setting or a situation with my Win 7 Pro.
The only thing that worked for me was to re-install Win 7 on a new drive. I got a good deal on a 1.5 tb WD from TigerDirect.com and then installed a fresh install of Win 7. It recognized all my drives and CD/DVD drives.
I also re-arranged my drive cables so that they were in order, i.e SATA 1, 2, & 3 and IDE 1&2. I don't think that was the thing that worked, but I didn't try my other Win 7 installation. The only bother is that now I two choices of Win 7 boot options. I figured out that the top one was my new install and the bottom one was the old install.
Good Luck, I wanted to increase my storage anyway, and it solved my drive recognition problem. There was or is probably a Registry edit that would have fixed the issue, but I did not see any specific directions online.
