2011 15.4" Macboo Pro Only Getting Sata II Speeds in Main Bay

[AML225]

I installed a Vertex 3 in my Macbook Pro's main hard drive SATA slot. All software and firmware are up to date but for some reason the drive is only connecting at SATA II 3Gb/s speeds. When I connected a Vertex 4 in the slot it was not detected at all.

Anyone have any idea what is going on?

I appreciate the help.

I read that thread actually. It just confused me more. The gist I'm getting is that I'm screwed?

Well your drive is clearly capable of SIII, but as the negotiated link speed is showing, it has been throttled to SII.
When did you get your MBP. Was it a CTO/BTO or a stock. Apple did do a running change in the chipset for the early 2011 15 and 17 in MBPs.

Purchased in June of 2011. Only upgrade was I purchased it with the 750gb drive instead of the 500gb. It's the 2.2GHz model.
