    That is an informational message not an error, it is nothing but indicates that an IO operation has been issued, and it has taken over 15 seconds for that operation to return through the IO subsystem. Have a look at this support article for troubleshooting steps: KBAhttp://support.microsoft.com/kb/897284/en-us
