That noise you just heard from outside Seattle was a collective sigh of relief, as Microsoft announced that it has released a public beta version of Power Pack 1 for Windows Home Server. It’s more than a service pack, with at least two significant new features (client support for x64-based Windows machines and the ability to back up data from the server to external media) and a long list of enhanced features. Under normal circumstances, I’d be writing first and most about those new and improved features and comparing the improvements to the initial release of Windows Home Server last year. But instead, I’ll be answering the question that every Windows Home Server user wants to know: Does this update fix the data corruption bug first announced late last year?
