On the Windows Home Server team blog they are reporting that a fix for the data corruption problems will be included in the Home Server Power Pack 1. Beta testers (including me) should get the fix sometime in April to try out.
The team is making great progress on the data corruption issue. We plan on releasing a beta of Power Pack 1 with the data corruption bug fix to our hardware and software Partners, Microsoft MVPs, Windows Home Server Insiders, and Microsoft Employees in April. And then based on feedback and additional testing, we currently plan on releasing a public beta in May. If you are interested in participating in a future public beta, go to http://connect.microsoft.com/WindowsHomeServer to register. When the Power Pack 1 software is ready for public testing, we will contact the people that have already registered at the Windows Home Server Connect site with more details on the public beta program.
