The error I receive when attempting to use the "sync" io engine in Windows 7: "fio: pid=4904, err=5/file:backend.c:633, func=full resid, error=Input/output error" I tried psync - that ran, but didn't seem to do the proper io. vsync didn't work at all. If there are no synchronous engines available at the moment for Windows, I suggest adding an option to simulate synchronous io when using the Windows AIO engine. Greg.
