I have my disk attached to an Asus M2NBP-VM CSM and it has the first gen SATA ports. The disk is use for file server purposes and the server 2008r2 is on another disk.
It works fine. For this reason I urge the user to consider a better quality motherboard

I should also point out that the SATA specs are very clear and it appears the VIA chipset/firmware is not compliant

VeganFanatic is absolutely right that the VIA chipset is not compliant to SATA specs, and this is exactly why it requires a jumper on any SATA II or III drives connected to it to force them down to SATA I speeds since the controller is incapable of telling the drive this itself. Where other SATA I controllers, like the one on VeganFanatic's Asus M2NBP-VM CSM, are able to cope with the situation because they were built properly to spec, both Marc_'s motherboard and mine suffer from flawed design.
The point here, however, is that both Marc_ and I went into our hard drive purchasing decision knowing full well that we require hard drives with this 1.5Gbps jumper feature in order for them to work with our motherboards. Because this feature is becoming more rare, we know that the onus is on us to do thorough research into the capabilities of a hard drive before we purchase it. In Marc_'s case, there was not enough information available from Seagate for him to be able tell one way or another whether this model hard drive supports being jumpered down to 1.5Gbps or not, so he ultimately had to return his drive for a refund rather than risk being stuck owning something he couldn't use. In my own case, I also found Seagate's online information to be inconclusive, but I took the risk and bought the drives anyway from a retail store in my area where I knew the return policy would be headache-free if I needed to bring back the drives. When I opened up the box, I found not only an instruction manual claiming that the jumper would work as I expected it to, but I also found a jumper itself provided in a little bag in the box.
VeganFanatic, I'd like to politely suggest that you re-read my first post in this thread because it sounds like you may have missed this part:
So, despite the fact that the installation guide states that this should work, and it names my VIA VT8237 chipset explicitly, and the retail package even comes with a jumper provided in the box, I could not get my SATA controller to recognize either of the two drives.
I don't take issue with Seagate for choosing to drop support for legacy hardware. If I were them, I wouldn't want to be bothered having to expend resources on an issue that affected a small minority of SATA controllers from two generations of technology ago either.
What I do take issue with is that Seagate's documentation does not properly reflect the fact that they have dropped the 1.5Gbps jumper feature. The information available on their website is pretty murky and grey about it, and the information that came in the same box as the hard drive was just flat out wrong. I don't think it's unreasonable to ask Seagate to fix that.

When I had the ST2000DL003 I examined it with a magifier lamp but could not tell if the jumpers were still still connected to the controller chip. As I needed to keep it in the shrink wrap bag (to return to the store) I could not test the jumpers with an ohm meter. If the wiring is still there then it's only a firmware update so that the jumper could be used.
I never thought to test the jumper block with an ohm meter. That's a great idea!
Since you piqued my curiousity about it, I broke out my meter and got to measuring...
As a control for this experiment, I used an older SATA II Seagate ST3160811AS, which is the hard drive that currently lives on my troublesome VIA VT8237 controller and has been there humming along fine for years now. I know that the jumper works on this drive because the VT8237 won't recognize the drive at all without the jumper in place, but it sees it just fine when the jumper is in place.
With all jumpers, connectors, and power removed from the drives, I took measurements across the jumper block pins:
ST3160811AS (control drive): 107K ohms
ST2000DL003 (experimental drive): out of range/infinite [using a meter range as high as 2M ohms]
So, it looks like nobody's home behind that jumper block on the ST2000DL003, and no amount of firmware tweaking is going to fix that.
