Well, when I got my 160GB hard drive and didn't install the Windows 2000 fix from the Western Digital website, there was no troubleshooting involved. My hard drive just got corrupted, and I lost all my data. Now that I know it's there to download, of course, I can avoid that little problem.
But I think Brit has a point. When it comes to stable releases, Microsoft isn't exactly the best. I don't know if I'd trust them with a new filesystem right away.
