Just as an additional update, I have recently changed the blog wording and removed the following line: This isnt to say that there wont ever be a fix for systems in a torn state but there are other higher priority fixes that are being worked on internally right now to assist with SP1 issues (dont ask what they are because I am not saying <G>).
I did this because it was brought to my attention that this implied a potential fix and that wasnt my intent. Sorry for the confusion. So to reiterate, if you have a system that has been in a torn state, the only supported method of repair is a reinstallation of the OS.
