It’s been 5 months since WHS was sold as a final complete working software program as RTM and OEM. And now that Microsoft cannot escape the fact that it’s underlying core and foundation base code known as WHS Drive Extender has a design flaw, isn’t it long over due and time to actually fix this once and for all?" Um, I believe that's exactly what they're trying to do - hence the June release date, as opposed to rushing a quick fix out now. “It’s been more than a year since the beginning of beta testing.

Microsoft has estimated that the fix will not be ready for another 3 months (June) and while it’s unlikely for this to take less time it can certainly take more. As of right now retailers are still selling OEM servers with 2+ drives (making them susceptible to the bug) and computer enthusiast retailers are still selling the OS itself, all with no notice about this bug.

WHS DE has a design flaw, and needs to be fixed. Just how much time does it take to fix the problem? It's been more than a year since the beginning of beta testing. It's been 5 months since WHS was sold as a final complete working software program as RTM and OEM.

I have indeed been running WHS on 2 drives for some months and have not come across it yet.

I ran a slow (Via C3) multidrive system for months without any problem. Did they change something in Drive Extender since RC1? Why didn’t this get caught during the multiple beta phases?

Based on my experience with the problem, it's a bug with the synchronization / replication of two copies across multiple drives. They are not synced immediately (the way they would be on RAID 1.) This leads to two versions of the same file that are both being modified in an asynchronous manner. I'll be glad when this bug is gone.
