Is it possible to ask Microsoft a technical question so as to get a correct and authoritative answer. I don't mind paying.
The question I want to ask is exactly what does FlushFileBuffers do in Windows 7 and Windows 8 for SATA drives. e.g. does it use "Flush Cache ext" and does it return only when data has been physically written to the drive. If not, is there any way to tell when the data has been physically written to the drive?
Is there a way to ask Microsoft a question like this?
