Hello,
I'm having what sounds like the same problem reported by Dallas Clement back in April- writes to a physical drive don't seem to do anything:
C:\Users\Administrator>"\Program Files\fio\fio.exe" --name asd --filename=\\.\PhysicalDrive3 --rw=write --size=1g --bs=64k --thread
asd: (g=0): rw=write, bs=64K-64K/64K-64K/64K-64K, ioengine=windowsaio, iodepth=1
fio-2.0.12.2
Starting 1 thread

Run status group 0 (all jobs):
C:\Users\Administrator>
Read works as expected (there may be a bug in the ETA display but I'm ignoring that right now). Using fio-2.0.12.2 on windows 2008, running in a cmd box. Unfortunately, I don't have windows dev tools readily available, so I'd prefer to stay out of the code. Thoughts?
Thanks,
z!
