I reformatted the 1.0TB last night (so I wouldn't lost my data) and did a fresh install of Windows 7. Within an hour of the first boot and update install, I got my first BSoD. So I'm totally ditching Windows 7 until SP1 or whenever I know there's drivers for everything on my computer that work. I'm fine on Vista for now
I haven't had any problems with Vista (SP2). None. Not one! I run it on four of my eight machines (Three are up to date desktops, two are Windows laptops, one of them a MacBook and the other two too old to run Vista decently)
After the BSoD on 7 I immediately put my Vista disk in and reinstalled. It's been running since about ten last night without any hiccups, so I'm happy
