| Event Information | Accroding to Microsoft: This event indicates that a single-bit error has been detected, and that this error has been successfully corrected in memory. In this scenario, the page where this error occurred may or may not have been corrected on the physical hard disk. The single-bit error is not corrected on the physical hard disk unless the page has been written to.
