Well I'm glad you got to the bottom of it
"BTW..... the Gsta ports if im not mistaken are top 2 grey ports on the mobo
I'm kind of having the same issues except the GSATA3 is enabled in bios but for some reason it stopped recognizing any drives attached to it. I have it set to AHCI and have a Crucial 256GB SSD and DVD hooked to it. I had to clear CMOS to get it to recognize the drives hooked to that controller again. This has happened twice so far.
