this is a little unfair and inaccurate
Firstly calling it WHS 2008, suggests its on the server 2008 / vista code base, its not. Its built on server 2003, SBS edition. The bug is deep in the way the server balances data across multiple drives, as this tech is WHS only it doesn't affect any other server OS. It also only affects a limited number of programs when used to edit files over a network share, the backup database, remote access etc are not effected.
Don't get me wrong, its a major bug and a 6 month fix is pretty poor, but its a clever tech and the bug doesn't make the server useless. Mine has done 2 bare metal restores so far, which is a life saver.
Paris as she maybe wrote the disk management driver and/or this article!
