A small blip on my laptop nothing to worry about, but a quick glance at the Event Viewer to reassure myself - yeah no problem. However my eye caught a warning from ESENT
Windows (3404) Windows: A request to write to the file "C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb" at offset 112828416 (0x0000000006b9a000) for 8192 (0x00002000) bytes succeeded, but took an abnormally long time (3587 seconds) to be serviced by the OS. In addition, 1 other I/O requests to this file have also taken an abnormally long time to be serviced since the last message regarding this problem was posted 441092 seconds ago. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem.I look at the time it was posted 13:59:48; hmm 3587 seconds that's about an hour. So "likely due to faulty hardware" or perhaps more likely that the Windows tried to write to this file just as I put the laptop into sleep mode to go out to lunch and didn't finish until I woke it up on my return.
Way to panic people guys :-)
