Anvil,

I'm starting to think the drives either like your motherboard or they hate it. End of story.

One consideration is the fact that I used the OS installation from the DP67BG mainboard. Windows 7 doesn't protest much (Office needs reactivation though), but I'm just running out of ideas. I'm running it with MSAHCI with this H67 for a while. I don't think the disconnect I had was a coincidence, but I'm just going to try it the H67 msahci combo for a little while. It didn't work very well with the other board and msahci is 6mb/s slower avg as well. I'm pretty sure I caused it, but the drive is just really "sensitive". I'd had another similar circumstance with the other board too. I'll take a crash every thirty hours over every eighteen, but I won't be happy about it.
