Have you tested the SATA cable to make sure that is not the issue?
Here's an update. I tried a Crucial M4 CT256M4SSD2 256GB SATA III on Port 1 and the BIOS did not recognize it either! But sure enough it did see a plan old Western Digital HDD.
So I guess I can rule out the Intel 510 SSD as the issue. Now I wonder what is up with that port?
Are you using the Z68 chipset or the Marvell SATA 6Gb/s port?
Thanks for the help, totally appreicated but I think I got it figured out.
I was able to get another P8Z68-V Pro board to try and sure enough on the new board it worked fine! So I'm guessing I actually had a bad port on the motherboard, rare but those things do happen once and while. Glad that's over!
