When certain programs are used to edit or transfer files that are stored on a Windows Home Server-based system that has more than one hard drive, the files may become corrupted. Microsoft is aware of only a very small percentage of users who have confirmed instances of this issue and believes that most users are unlikely to be affected. Microsoft has established that this issue may occur when one of the following programs is used to edit, transfer, and save files to the home server:
- Windows Vista Photo Gallery
- Windows Live Photo Gallery
- Microsoft Office OneNote 2007
- Microsoft Office OneNote 2003

CAUSE – TECHNICAL DETAILSWindows Home Server uses a file system mini-filter driver in addition to the NTFS file system to implement Shared Folders storage technology. File system mini-filter drivers are an extensibility mechanism that is provided by Windows to enable storage scenarios. For distributing data across the different hard drives that are managed by Windows Home Server, the Windows Home Server mini-filter driver redirects I/O between files that are stored on the main hard drive and files that are stored on other hard drives. This redirection mechanism is enabled only when Windows Home Server is managing the Shared Folder storage of multiple physical hard drives. A bug has been discovered in the redirection mechanism which, in certain cases, depending on application use patterns, timing, and workload, may cause interactions between NTFS, the Memory Manager, and the Cache Manager to get out of sync. This causes corrupted data to be written to files. More information about the storage technology can be found in the following technical brief:
