If your Windows Server 2003 has more than 10 disks installed, and an event wants to log a message that contains \Device\Harddisk12, it will appear as \Device\Harddisk1 because the size of the logged data, driver name, and device name exceeds the maximum size allocated.

This behavior will impact event ID 7 and event ID 11 messages.

To workaround this behavior, use hardware diagnostics to determine the drive with the reported problem.
