It wasn't all that long ago that Microsoft unviled Power Pack 1 for Windows Home Server, which among many improvements, fixed an important data corruption issue. Microsoft today released another important patch for Windows Home Server owners, putting behind them what will hopefully be the last of problems associated to data storage and management on the Home Server OS.
As described in Microsoft Knowledge Base article 950193, unpatched users running PP1 could cause files in duplicated folders to become unrecoverable if a hard drive goes unexpectedly missing or fails. The severity of the issue is unknown, or how likely you are to experience any data loss as a result of these events, as the typical user doesn't usually yank drives from the Home Server without removing it properly through the OS. Drive failures are a fact of life in disk based storage, but are hardly an everyday occurance for users. The short time between PP1's release and the patch today means that few users would have seen this problem.
Regardless, any issue that can affect your precious data shouldn't be overlooked. Take the time to run Windows Update on your Home Server today and obtain the patch. If you're unfamiliar with how to do this, follow these instructions:
If the Automatic Updates feature is enabled on your home server, the update will be automatically downloaded to your Windows Home Server computer through Windows Update. Or, in the Windows Home Server Console, you can click Update Now on the General page of your home server Settings.
