These events may be logged if high-volume disk I/O operations are performed AND a time-out occurs while the LDM (Logical Disk Manager) is interacting with PNP (Plug and Play).

These messages can be safely ignored as they DO NOT indicate a problem with your computer. The time-out DOES NOT adversely affect your computer.
