Some files may be unrecoverable when a hard drive is removed incorrectly or when a hard drive experiences a physical failure on a home server that is running Windows Home Server Power Pack 1

You have a home server that is running Windows Home Server Power Pack 1. When a hard drive is reported as missing from a health notification in the Windows Home Server Console, files that are in shared folders may be unrecoverable if the shared folders have Folder Duplication enabled.

This issue occurs for one of the following reasons:

• A hard drive on the home server was removed incorrectly.
• A hardware failure has occurred on a hard drive.

To avoid this issue, you must use the Remove a Hard Drive Wizard before you physically remove any hard drives from your home server. The Remove a Hard Drive Wizard is available on the Server Storage tab of the Windows Home Server Console.

Windows Home Server helps protect users from the incorrect removal of a hard drive or the physical failure of a hard drive. A bug was discovered that relates to how Windows Home Server Power Pack 1 manages file duplication when a hard drive is incorrectly removed or when a hard drive experiences a hardware failure.

An update for Windows Home Server is available on the Microsoft Windows Update Web site.
